I have seen quite a few GW NFL jerseys that look as if they would be really tight on the actual players. I don't want to single any jersey out because I don't think there is anything wrong with these jerseys I've seen, I just don't understand how a linebacker or defensive linemen can wear a size 42 or 44.

I've also seen Giants GW jerseys from their Pro Shop page and the jerseys for their O-linemen look like they could fit WR's.

Does anyone have any idea why this is?
