I have to agree. How many NFL players don't play a game of basketball at some point in the offseason? In fact, my guess is that the reason you hear about bball injuries so much is simply because it's the most popular offseason athletic activity. If everybody in the league were, say, going ice climbing or cave diving or racing motocross, the consequences would be far, far worse.
Or to put it another way...you know how everybody raves about all the soccer Welker puts in to improve his footwork? If tomorrow he tears his achilles playing soccer, does that mean he's been an idiot all along?
Anyway, best wishes for good health to Spikes.
