I'm guessing Donahoe didn't get this guy for the debate team:
Mental capacity a concern; scored a 10 on Wonderlic Test.
From ESPN insider take:
Strengths: Explodes off the line, has the quick first step to drive defenders back and can get open quickly. Plays with good toughness, isn't afraid to go over the middle and has shown the ability to hang onto the ball after taking the big hit. Can catch balls thrown outside frame and rarely drops passes that should catch. Has great speed and shows a second gear when tracking the ball downfield. Shows outstanding change of direction skills, has the elusiveness to make multiple defenders miss in the open field and is always a threat to make a big play after the catch. Is a very dangerous return man and should make an immediate impact on special teams. Regained starting job after losing it early last year and has shown good perseverance.
Weaknesses: Is vastly undersized, lacks the height to compete for jump balls downfield and isn't much of a threat in the vertical passing game despite speed. Lacks the wide frame to shield defenders from the ball and isn't much of a red zone target. Has some problems getting a clean release working against press coverage and physical corners will have success muscling him out of routes. Lack of prototypical size makes durability a significant concern and had some problems staying healthy at the collegiate level. Mental capacity a concern; scored a 10 on Wonderlic Test.
Overall: Parrish red-shirted in 2001. He returned punts and started three games at WR in 2002, catching 14 passes for 271 yards and one touchdown. He provided excellent depth and returned punts in 2003, finishing with 24 catches for 322 yards and two touchdowns. He moved into the starting lineup in 2004 and finished the season with 39 receptions for 630 yards and eight touchdowns. Parrish also returned 17 punts for 252 yards and one touchdown last year. Parrish is extremely undersized and, as a result, he may never develop into an outside starter. However, Parrish has the potential to develop into a sure-handed and shifty slot receiver that can also contribute as a punt return specialist. As a result, Parrish grades out as a second or early-third round prospect in the 2005 NFL draft.
