It's the grammar that pisses me off more than anything, there.
Also - I don't think it was "injuries" per se. I think it was controllability, including with respect to his training and workout regimen. Sammy refuses to take direction about how to prepare his body during the offseason and, combined with the explosive way he plays, it results in significant wear and tear on his lower body. I don't know, but I'd be willing to bet, that the new training staff already had become exasperated by Sammy's lack of buy-in to their strength and conditioning program.
Still hate the trade, though...
