Get out there and play Dez, enough of this nonsense. He can't hurt it any more than he has, what is the point of resting a guy with that type of injury. Rub some dirt on it, suck it up and show what your made of. Players today are a bunch of pansies. Give me the good old days where players really played hurt.
You do realize these guys get paid a whole bunch of money that counts against a salary cap that didn't exist back then, right? So when these "assets" are out for long periods of time it not only hurts the team on the field that week but also limits the team's ability to replace that asset with another asset of comparable quality.
Even if "he can't hurt it any more than he has", have you stopped to consider he might injure himself trying to compensate for it? I've done this several times where I've thrown my back, hip or other leg out of whack trying to compensate for another injury.
I get the "be tough" notion, but its also a very complicated business model for the team to manage its cap and put a high-quality/competitive team on field.
