A few things here....(assuming your talking about Oher)
1) It was 21 times
2) He is nearly a foot taller then you are (5'9 vs 6'7)
...2a) I believe his wingspan is actually wider then 6'7
3) They don't train bench pressing.
As a football movement, bench press is the third most important lift. #1 is Power Clean, and #2 is Squat. I've talked to several D-1 strength coaches (well, listened more then talked) and none of them really considered the bench press an essential. To them, it's the best upper body pushing movement, which is pretty low on the list of importance.
As another reference, Shaun Rogers (DT-CLE, former all-pro) failed on 22 reps during a pro-bowl competition. Hasn't really effected him.
Obviously it's pretty disappointing when a man that big fails to get 30 reps. It's just not that important. His athletic abilities will mean far more (shuttle, 40 ect..) then his strength.
