Sometimes, late at night, I Google Latrell Sprewell. I don’t really know why. Some vague longing. It’s been going on since he slipped out of the N.B.A., and the public eye, in 2005. At first, I was looking for news of his return. After a while, I was looking for any news at all. One would have thought that the recent first-round matchup between the Heat and the Knicks would have been the occasion for an update, but this was not the case.
