that behavior you abhor (faking injury) is just to easy to get away with. Tyrd will say his injury is real and I doubt any of his fellow players will question him or ask for proof. Tyrd says something just ain't right with his foot and his fellow players won't question it. of course he isn't going to flaunt the fact that if he had a long term contract, he would play through what ever was nagging him.
let's take a recent example for the Bills. last year, prior to the bye week, Mario Williams repeatedly and often complained/mentioned to the press about his wrist bothering him. Yet the bills never included him on their injury report. in fact they were saying it was all in his head. got to the point where the NFL started an investigation of the Bills and their reporting of injuries. Mario went and had a second opinion away from buffalo. had surgery during the bye week and started playing better immediately after.
during that whole episode , not one player called Mario out. even though the Bills, including his head coach, publicly suggested he wasn't really injured.
