LB Josh Kaddu, Round 5
Kaddu never redshirted at the University of Oregon and was a starter for the last two years after he put on 30 pounds of muscle as a junior. As a strongside linebacker for Oregon, Kaddu earned All-Pac-12 Conference honors in 2011 when he started 14 games and recorded 50 tackles, including a career-best 6.5 sacks and 9.5 tackles for loss.
He played strongside linebacker at Oregon, but he's got enough athletic ability to line up on the weak side as well in the Dolphins defense. In the early going, Kaddu's biggest contribution is likely to come on special teams.
B.J. Cunningham, Round 3
After redshirting in 2007, Cunningham became a starter right away and left Michigan State as the school's all-time reception leader. His numbers increased every year, from 41 in 2008 to 48, 50 and then to 79 as a senior in 2011. Cunningham averaged an impressive 16.5 yards per catch last year and scored 12 touchdowns.
After the trade of Brandon Marshall to Chicago, the Dolphins were left without a true No. 1 receiver, which Joe Philbin has said is no big deal in his offense. Cunningham clearly isn't going to be a No. 1-type guy, but he's said to be an ideal receiver for the West Coast offense because of his physicality and his ability to catch the ball in the middle of the field. Cunningham is the type of receiver the Dolphins don't have many of on the roster, so he's got a good chance of seeing plenty of action early despite being a sixth-round pick.
DT Kheeston Randall, Texas
After beginning his college career as a defensive tackle, Randall started his final 35 games as a nose guard. He earned All-Big 12 Conference honors twice while at Texas. Randall had four career sacks and two blocked kicks in 2010 — a blocked extra point against Oklahoma and a blocked field goal against Florida Atlantic.
Randall may have played nose tackle in his last two seasons at Texas, but the Dolphins are expected to feature more of a four-man front next season. Randall is a good fit in that scheme, too, because of his run-stopping ability. He has compared his game to that of Minnesota DT Kevin Williams, and he's got a similar type of build. As a seventh-round pick, Randall is no lock to make the team, but he could earn a spot as a backup behind Paul Soliai and Randy Starks, particularly if Jared Odrick winds up at defensive end in the 4-3.
WR Rishard Matthews, Nevada
Matthews spent two seasons at Nevada after transferring from Bakersfield College and put up some impressive numbers, particularly in 2011. Matthews caught 91 passes for 1,364 yards and eight touchdowns. Matthews also had a punt return for a touchdown in both 2010 and 2011, as well as two rushing touchdowns in 2010. He was a first-team All-WAC selection last year.
Matthews is the same type of receiver as B.J. Cunningham, meaning he's a good fit for the West Coast offense. The one difference with Cunningham is that Matthews also could help out as a punt returner. As a seventh-round pick, Matthews will have to fight to make the roster, but his versatility and physical attributes should give him a chance.
