I'm not convinced his condition will prevent him from playing 30 minutes, it will prevent him from playing with the explosiveness and athleticism he did before. It's not like he will be able to be explosive for 15 minutes a game. His knees just don't allow it, period. He will have to learn to play at a certain speed and level much different than he did before.
it lowered the cap so big markets can no longer be good/interesting. basically, they want everyone to suck equally. why? because even with big markets always getting big time free agents, small markets could still make great teams through the draft. that is no longer possible, OKC is the perfect example. they drafted so well that they can't even resign all their talent because the luxary tax would fuck them in the ass.
