Defensive End/Tackle
San Jose State University Spartans
6-5, 288
Chino, California
Chino High School

The Chino, California native has been rapidly moving up National Football League draft boards, especially after his stellar 2008 campaign and post-season all-star game showing. Blessed with impressive size and quickness, his versatility has the many professional teams feeling that he can fill a variety of roles on their front line.

The son of former New Orleans Saints offensive tackle, Daren Gilbert, Jarron's on the football field might have garnered him the attention of the NFL, but it was his recent display of athleticism that has made him a YouTube "sensation." While working out with his trainer after the 2008 season, he was told that former St. Louis Rams safety Adam Archuleta could jump out of a swimming pool.

Gilbert then proceeded to get in the pool at a teammate's apartment. From the shallow end of the pool, he amazed everyone by simply jumping out. "I went out there one day – it wasn't that big a deal to me – and I just went and jumped out of the pool. I found out that I could do it, so I put it on film to make everybody else believe me," Gilbert simply stated.

Gilbert can thank his bloodlines for his athletic ability. While attending Chino High School, he lettered in football, basketball and track and field. The two-way lineman earned All-Sierra League honors on the gridiron. As a forward, he was also an All-League choice for the basketball squad. He also handled the weight for the track squad.

The 240-pound defensive lineman enrolled at San Jose State in 2004, spending the season performing on the scout team and working out in the training room. With ten pounds of muscle added to his frame, the red-shirt freshman started four of the eleven games he appeared in, lining up at right defensive end in 2005. He posted 22 tackles (14 solos) with three sacks and five stops for losses during his first varsity campaign.

Gilbert shifted to left defensive end in 2006. Now weighing 270 pounds, he started ten of thirteen contests, coming up with 32 tackles (14 solos) that included five sacks and 7.5 stops behind the line of scrimmage. He also used his impressive wingspan to deflect six passes, tops among the down linemen in the Western Athletic Conference.

In 2007, Gilbert started all twelve games, seeing action at both right defensive end and tackle. The All-WAC second-team choice, continued to add bulk and strength, listing at 280 pounds. He led the team's down linemen with 38 tackles (23 solos). He collected 7.5 stops for losses that included four sacks, as he also broke up four passes.

One of four team captains, Gilbert received All-American, All-WAC, conference co-Defensive Player of the Year and team MVP honors in 2008. Now measuring in at 290 pounds, he started all twelve games at left defensive tackle. He registered 52 tackles (36 solos), leading the nation with 22 stops for losses of 116 yards. His 9.5 sacks led the Spartans with 9.5 sacks, the second-best total in the league.

Body Structure
Gilbert has a big build, with a solid midsection, wide waist and hips, broad shoulders, big bubble, muscular calves and thick thighs. He does have good speed, but he needs to get better stamina, as he runs out of gas late in games. If he is to be utilized as a defensive end, he might be better served losing about ten pounds, so he can generate better change of direction agility. If he is to perform as a defensive tackle, his frame might be better suited to add bulk than drop it.

Athletic Ability
Gilbert has the balance and agility to shoot the gaps and make plays in the backfield, showing good lateral pursuit ability. He is a strong wrap-up tackler who is still working on developing better hand usage, but he compensates with excellent playing strength. He is an athletic in-line pass rusher who plays a variety of positions. He will generally line up as a left defensive tackle, but has seen action at both end positions. He can even stand up and come off the edge at times when asked to blitz. He is also used to cover the running back in the second level, but lacks the foot speed to be effective doing that. When he is used as a drop end, he shows good awareness. He can make plays working down the line, but lacks overall hand usage…GRADE: 7.2

Football Sense
Gilbert picks things up quickly, evident by his ability to play any position on the front wall. He has decent instincts, but needs to play with better consistency, as he will disappear for stretches. He appears to have the ability to read and react to the play in front of him. He shows strength in his anchor vs. double teams, but there are stretches in games where his face should be plastered on a milk carton. He picks things up quickly in practice and then performs them well in the game…GRADE: 6.1

His coaches call him a good person with no off-field issues. He is a good team leader, vocal and always has a pleasant attitude. His father, Daren Gilbert, was a star player for Cal State Fullerton and offensive tackle for the New Orleans Saints (1985-88)…GRADE: 6.3

It is not as if Gilbert is not competitive, as he does show good urgency closing when he locates the ball, but his motor runs hot and cold. Perhaps due to stamina issues, he does disappear for stretches. When the "light goes on" upstairs, he can completely dominate a game, but he really never put it all together until the second half of his senior season. He needs to show more consistency, as he does get washed out when he leaves his chest exposed (usually happens when he tires late in games) and does tend to play at a high pad level, needing to do a better job of sinking his pads…GRADE: 6.0

Work Habits
Gilbert is compliant, listens well and takes to hard coaching. He was the defensive captain as a senior, but still needs to develop more maturity, both physically (stamina issues) and mentally (disappears for stretches)…GRADE: 5.8

Gilbert has adequate explosion off the line of scrimmage to cause trouble in the backfield, but can be inconsistent. He flashes good quickness working in-line and has enough strength to win the battle at the point of attack. Offensive tackles generally have their work cut out for them, as Gilbert can be explosive when he stays low in his pads, but late in games, he seems to have stamina issues. Even when he plays at full speed, he might lack the suddenness to play on the edge. He does a much better job of getting to the quarterback shooting the gaps than when having to loop around the corner…GRADE: 5.7

Strength at Point
At his primary position, defensive tackle, Gilbert might lack ideal bulk, but he has a developing frame to add the necessary pounds to play inside. He has those outstanding, long arms and the strength to control his side of the football, can hold ground at the point of attack and clog rush lanes, when he does not play high in his stance. He shows good ability to stymie double teams, with a strong base to anchor. When he gets too high in his stance, he will yield ground, though. He will generally play with leverage, but he gets frustrated when his initial move fails (will give up and get absorbed by the offensive tackles). When he recovers off blocks, he can be very disruptive…GRADE: 7.5

Use of Hands
While Gilbert has good hand strength, he sometimes fails to recoil and reset quickly, causing him to get tied up too long. He is best when using his hands to contain rather than shed. He leaves himself exposed quite a bit, giving up body surface coming off the snap. His best hand move is his swim move to slip past blocks on the pass rush. He has also been quite successful using his wingspan to break up passes at the line of scrimmage… GRADE: 6.3

Lateral Pursuit/Effort
Gilbert has the ability to slide down the line and make plays at the Xs. He has the balance and change of direction agility to work back to the cutback lanes, but is better playing between the tackles that trying to get out and make plays along the sidelines. He shows good lateral movement down the line of scrimmage and is effective chasing from the backside. He was inconsistent in this area for most of his career, but showed great improvement the second half of the 2008 campaign (see New Mexico State, Boise State, Idaho and Louisiana Tech games). His problem arises late in games when he has his usual shutdown of his motor…GRADE: 6.3

Tackling Ability
Gilbert is a strong tackler delivers a solid block to blockers with his hand swipes. He is an effective short area hitter who delivers a punishing blow and shows power making the wrap-up tackle. When he hits a ball carrier or quarterback, he does it with force and you can hear the impact…GRADE: 6.8

Run Defense
Gilbert needs to use his hand punch more often and must do a better job of keeping those hands inside his frame. He has the upper body strength to impact a ball carrier with a good thud. He will drop his hands quite a bit, which lets blockers get into his chest. This is an area that I feel will see him be a better fit at tackle in a 4-3 defense or align outside as an end in a 3-4 formation. He plays at a high pad level, using his strength effectively to push the blockers back through the rush lanes. He has the short area burst to string plays wide. When he stays at a good pad level, it makes it very difficult for defenders to move him off his anchor. On 41 running plays in 2008, he allowed only 39 yards and just four first downs in 2008…GRADE: 7.2

Pass Rush
Gilbert is not a consistent pass rusher, but during his senior year, he finally started using his hands better, developing better bull rush skills. Like Richard Seymour (New England) and John Henderson (Jacksonville), he might be better served as a tackle, as he does a good job of working on the offensive guard's edge. He has that short burst needed to penetrate, but until the second half of the 2008 season, it was too inconsistent. The light might be finally coming on here…GRADE: 6.6

Closing on the QB
In the short area (shooting the gaps at tackle), Gilbert has a good burst to close and can accelerate in the backfield, but usually does this best vs. a stationary blocker. He does not have the suddenness or blazing speed to take a wide loop coming off the edge and still seal the deal on the QB, making him a better fit inside than at end. What he excels at is getting his big body in the passer's face and using his reach, wing span and leaping ability to deflect quite a few passes at the liner of scrimmage…GRADE: 6.4

Gilbert is very athletic, using his size and speed to close down the backside with the strength to control. He is not the type that can explode off the edge and get into backfield to push the pocket as an end, but lining up inside, he plays with better leverage. He has the ability to locate the ball once he gets free from his initial blocker. He is better at the line of scrimmage than when on the move in attempts to locate the ball. He wins the initial battles, but sometimes will shut down when his first move fails…GRADE: 6.3

Compares to ...
TY WARREN-New England…I see Gilbert more as a 3-4 defensive end rather than an edge rusher in a 4-3 alignment. He seems more comfortable shooting the gaps to get to the quarterback rather than trying to loop around the edge. If taken by a 4-3 defense, he will be better off playing inside. He has a lot of potential and a rare sized frame with an excellent wingspan, but it took more than three seasons for him to start to produce. It could have been due to him settling in at defensive tackle in 2008.
