Mostly agree with your rankings; with the optimism bias from being a cardinals fan personally, I'd argue you could make a 1 star increase at each position, but their current rankings are also fair. I very much disagree with the 1 star ranking at special teams however, as we have a pro bowl gunner in Justin Bethel being joined by some high upside athletes in the kick coverage team and kick return game. Probably the best coverage unit in the game, which coupled with a punter who is below average (don't think he's as bad as stats show- his hangtime is rediculous, and it seems the staff went with him for this reason. I'd choose a distance leg with our coverage team, butI digress). In short, I'd say 3 stars is fair. A perfectly average special teams unit, whose only limitation really seems to be Drew Butler's distance and the uncertainty of a new long snapper (but both seem pretty reliable this far)
Here's a list of prospects who improved and worsened their draft stock in the Senior Bowl (listed alphabetically).
2008 NFL Draft Stock - On the Rise
Tashard Choice, RB, Georgia Tech (1/27)
Height: 5-10. Weight: 210. 40 Time: 4.48. Projected Round: 2-3.
Tashard Choice was the best running back at the Senior Bowl, running over defenders while showing quickness. He definitely made himself a candidate for the second round.
Early Doucet, WR, LSU (1/24)
Height: 5-11. Weight: 211. 40 Time: 4.49. Projected Round: Top 25 Pick.
With an excellent week of Senior Bowl practice, Early Doucet has emerged as the top senior in the class and a sure-fire first-round pick.
Sedrick Ellis, DT, USC (1/27)
Height: 6-1. Weight: 308. 40 Time: 4.83. Projected Round: Top 3 Pick.
Sedrick Ellis was a man amongst boys at the Senior Bowl, effortlessly pushing the opposing offensive line around as if they were small children. Ellis was simply unblockable. It wouldn't surprise me if the Dolphins or Rams took him first or second.
Lavelle Hawkins, WR, California (1/27)
Height: 5-11. Weight: 187. 40 Time: 4.43. Projected Round: 2-3.
Lavelle Hawkins made a great adjustment on the fly, catching an underthrown Chad Henne pass in the end zone at the Senior Bowl. This is just an example of how well Hawkins did all week.
Trevor Laws, DT, Notre Dame (1/27)
Height: 6-0. Weight: 297. 40 Time: 4.98. Projected Round: 2.
If it weren't for Sedrick Ellis, Trevor Laws might have shined as the most impressive defensive lineman at the Senior Bowl.
Leodis McKelvin, CB, Troy State (1/27)
Height: 5-10. Weight: 190. 40 Time: 4.38. Projected Round: Top 10 Pick.
Leodis McKelvin didn't play much in the Senior Bowl, but he had a great week of practice, showing that he's capable of playing with the top athletes in the country.
Dominique Rodgers-Cromartie, CB, Tennessee State (1/27)
Height: 6-1. Weight: 183. 40 Time: 4.37. Projected Round: Top 15 Pick.
Wow, how was this guy not recruited by any BCS schools? Dominique Rodgers-Cromartie covers well, makes big plays and tackles extremely well. He's tall and runs a 4.3. Excluding Sedrick Ellis, Rodgers-Cromartie made the most money at the Senior Bowl, moving himself into the Top 15.
Chris Williams, OT, Vanderbilt (1/27)
Height: 6-6. Weight: 320. 40 Time: 5.13. Arm: 32 7/8. Projected Round: Top 20 Pick.
Mike Mayock labeled Chris Williams as his No. 3 offensive tackle in this class. After a solid Senior Bowl, Williams very well could be the third tackle taken.
2008 NFL Draft Stock - On the Decline
Colt Brennan, QB, Hawaii (1/27)
Height: 6-2. Weight: 185. 40 Time: 4.84. Projected Round: 6-7.
Prior to the Senior Bowl, I had Colt Brennan as a fourth- or fifth-round prospect. Now, I'm thinking that was too high. Brennan really sucks. He has no arm strength. His side-arm release is troublesome. His attitude sucks (take off that rainbow visor and stop drawing attention to yourself). He has character issues. I'm not even sure if he gets drafted at this point.
Titus Brown, OLB, Mississippi State (1/24)
Height: 6-3. Weight: 239. 40 Time: 4.68. Projected Round: 4.
Titus Brown weighed in at 239 pounds at the Senior Bowl, meaning he'll be limited to linebacker at the next level. This is pretty disappointing from a prospect who seemed so promising.
Dorien Bryant, WR, Purdue (1/27)
Height: 5-9. Weight: 169. 40 Time: 4.37. Projected Round: 5.
A couple of months ago, I heard some people compare Dorien Bryant to Steve Smith - an undersized receiver who would surprise people at the next level. I just don't see it.
Kory Lichtensteiger, C, Bowling Green (1/27)
Height: 6-2. Weight: 296. 40 Time: 5.16. Arm: 30 7/8. Projected Round: 5.
No one played well against Sedrick Ellis, but Kory Lichtensteiger looked so helpless, it was as if a 12-year-old were blocking USC's monstrous nose tackle.
Marcus Smith, WR, New Mexico (1/27)
Height: 6-0. Weight: 214. 40 Time: 4.46. Projected Round: 6.
Whether it was at practice or in the actual game, Marcus "Hands of Stone" Smith couldn't catch anything.
