Report: NFLPA would fight against pad proposal
A source told Marvez that the league has not provided proof to the NFLPA that the pads would have any effect on player safety, though the union has asked for it.
Marvez reported that another possible issue…is that players will resist being forced to wear leg padding out of vanity or concern that the padding will negatively affect their ability to perform—even if the intended goal of requiring pads is to keep the player on the football field.
“Guys want to feel as sleek as possible,” NFLPA President Domonique Foxworth told FOXSports.com last year. “Anything that inhibits that makes them feel it’s slowing them down or getting in their way. Some guys have never played with those pads. It’s difficult for them to wrap their heads around it mentally.”
It's not clear how wearing knee pads will help with player safety, although one assumes they won't hurt.
Let's be honest, though. The NFL has a lot of legal reasons to demonstrate they really care about player safety at the moment. If this includes forcing players to wear more padding, they are going to do it.
The biggest holdouts, of course, will be the corners and wide receivers. Like a group of hot chicks going out on the town, if they don't feel just right in their clothes, they may not come to the party.
