Greg Gabriel, Bears director of college scouting, admitted Brown had the talent to be a high round pick it is his consistency that needs work.
"He looks great one series looks like he can be a super player and then he takes some plays off the next time," Gabriel said.
Brown admits he has been inconsistent at times, but is ready to work.
"I think every player can be more consistent and hustle a little bit more," Brown said. "I'm going to do my best and give everything I have got, 110 percent every play and hopefully I can make the fans of Chicago and the team proud.
"I want to get rid of those thoughts. I don't want Chicago to think I do those things (take plays off). They took a chance on me so I want to make sure that I don't make them look bad."
Brown said he was disappointed that he fell to the second day in the draft, but he was happy where he wound up.
"I went to the team that I wanted to be on all along," Brown said. "I really wanted to be a Chicago Bear so that helped a lot."
Anther reason Brown fell to the fourth round was limited ability to play the run. Most likely he'll be a situational pass rusher, who won't play more than 10-15 plays a game. Gabriel said there is a chance Brown can become an every down player.
One thing Brown isn't lacking in is confidence.
"I know I can (be an every down player), I just need a chance and I have one and I'm very grateful."
Brown Bio Notes: Three-sport athlete (football, basketball, track) in high school who played quarterback and linebacker. Redshirted at linebacker in 1997 and backed up Jevon Kearse in '98. Started 9-of-12 games at defensive end in '99 and won All-Southeastern Conference honors and was a Lombardi Trophy semifinalist. Started 11-of-12 games in 2000 and won All-SEC honors for the second year in a row. Had 10 tackles and two sacks in '98; 45 tackles, 13 for loss, with two interceptions and five fumbles caused in '99; and 56 tackles, 7 1/2 sacks and one interception in 2000, and 50 stops, including 13.5 for loss and 10.5 sacks in '01, when he was a consensus All-American, Associated Press SEC Defensive Player of the Year and an Outland and Nagurski finalist.
Positives: Excellent athlete. Has the athletic ability and movement skills to play linebacker. Can drop into pass coverage. Greatest strength is coming off the edge and rushing the quarterback and has also developed a nice inside counter move. Can be a top pass rusher. Has terrific initial quickness, excellent speed, an explosive burst and second gear and the ability to change directions and to redirect. Plays fast and can explode off the edge. Uses hands well.
Negatives: Undersized and will have trouble at the point of attack at times. Gets wired to and engulfed by big tackles at times. Needs to add more pass-rush moves. Does not always play hard or know what to do when he gets held. Will loaf in pursuit. Hot-and-cold player who at times will disappear if you shut him down early. Tends to feed off success and let failure get him down. Does not always hustle or chase the play. Loves sacks and at times gets a little lax about playing the run.
Summary: Can be a top pass-rush specialist if he learns to play hard all the time, develop his moves and not get down when he gets blocked and negated early in the game. * Player biographies are provided by Pro Football Weekly.
