There is a lot of bad information on here.
Let's start by getting rid of the staff asked him to lose weight. Didn't happen.
I went back and did some checking.
Entering his senior season at TCU he was listed at 250 lbs.
Entering the draft he was listed at 263 lbs.
His first two years in Buffalo listed 265 lbs.
The next three he was listed at 263 lbs.
In 2006 he was listed at 262 lbs.
In 2007 on he's listed at 243 lbs.
Why the weight changes? It could be they are finally being honest about it. When I was in college I played basketball. One game I was listed as a 6'6" 210lb shooting guard - I'm 6'2" and was about 185 lbs. Either way - I'm sorry because I might be naive on this but in no way shape or form do I believe the soft spoken tree farmer from Texas Christian EVER used steroids so that's out too.
Additionally, I know this topic came up last year and Schobel specifically addressed it. He said he was actually lighter than his list weight when at TCU. He put on weight for the combine. The Bills used that weight for his list weight even though he has been playing around 240 for basically his entire career. That he did lose weight but it was fat and that the Bills are always and have always been on top of his BMI and his body fat to muscle ratios and has been right around the same levels just about his entire career. Oh and he added the Bills finally listed his real weight.
One player you might compare that to is Jason Taylor. He's listed at 244 but has played almost his entire career between 230 and 235.
Since 2001 - player - listed weight - total sacks - average
Dwight Freeney - 268lbs - 70.5 sacks - 10.07 per year over past 7 years
Michael Strahan - 255lbs - 79.5 sacks - 11.36 per year thru 2007
Jason Taylor - 244lbs - 89.5 sacks - 11.19 per year over the past 8
Kyle Vanden Bosch - 278lbs - 39.5 sacks - 4.94 per year over the past 8, missed one yr so 5.64 over 7
John Abraham - 263lbs - 79.5 sacks - 9.94 per season
Julius Peppers - 283lbs - 70.5 sacks - 10.07 per season over past 7 years
Robert Mathais - 245lbs - 53.5 sacks - 8.92 per season over the past 6 seasons
Darren Howard - 260lbs - 49.5 sacks - 6.19 per season over past 8
Aaron Kampman - 265lbs - 50.5 sacks - 7.21 per season over past 7
Shaun Ellis - 285lbs - 53.5 sacks - 6.69 per season over last 8
Patrick Kerney - 272lbs - 72.5 sacks - 9.06 per season over the past 8
Aaron Schobel - 243lbs - 68 sacks - 8.5 per season over the past 8 - take out last year and it's 9.57
He may not be the top pass rushing DE in the NFL but he has been one of the most productive since he came into the NFL, one whose salary is on par with his production when compared to his peers and one who has had little help from the other side. I would expect with his health returned this year he will be back among the top pass rushing DEs once again.
