here's a quick comparision of combine numbers (since i can't do video here):
Code:
Name Hgt Wgt Vert Reps 40 time shuttle 3cone broad jump
Mario Williams 6'7" 295 40.5" 35 4.70 4.37 7.21 10'0"
Kamerion Wimbley 6'4" 248 38.5" 24 4.61 4.48 6.98 10'9"
Tamba Hali 6'3" 275 30" 18 4.87 4.31 7.28 8'10"
Mathias Kiwanuka 6'6" 266 32" 17 4.70 4.15 7.29 10"0"
Ray Edwards 6'5" 273 39" 30 4.81 4.59 7.71 9'6"
Manny Lawson 6'6" 241 39.5" 23 4.43 4.21 6.90 10'4"
mario's 4.7 might not seem impressive, but he's doing that at 300lbs... the fastest OGs and DTs (near 300lbs) run 4.9-5.1. The best day 1 OT/OG/DT runs a 4.95 (eric winston, who also played TE in college). no one else breaks 5.00. There's another ex-TE/project C in chris chester that runs a 4.85 at 300lbs, but he might slip into day two. There just aren't many 300lbs DEs that are fast enough to pass rush, but he can.
The only guys that can outrun him weigh 50lbs less. He outjumps and outlifts anyone though, and is very competitive speed-wise even with the extra weight.
