Am I the only one who thinks that comparing his numbers w/those of a powerlifters is like comparing apples and oranges (to a certain extent atleast)?  You guys are finding the idea of him benching that much hard to believe, however he obviously uses a different form and timing than what would be used say, at a PL comp.  Not to take away from his strength at all, but its aimed towards a specific aspect of lifting/life that he NEEDS to excel at for his job.  Do you think they would allow his form (the way it's described in the article) at a comp?  It seems to me he would be DQ'ed in a second.  But I guess thats just me.
As to judging his weight, the idea seems absurd to me that anybody could accurately guess someones weight by staring at him in a picture, or a tv screen.  Regardless though, the guy would not be starting in the NFL if he weighed 185.
