Your question seemed more rhetorical than anything, which is why I didn't bother answering it. I'm not saying that he should save 4 timeouts...but most basketball coaches would want at least one time out just in case the game HAPPENS to be close (and based on the momentum, it would have been).
But if I am a coach, I would remember to save a timeout if the game is going to be close or even reachable...and it was reachable for the Blazers. He had terrible management of the time outs.
Your question is moot, since Nate's timeout he had to take as a result of a substitution mistake did not make any sense whatsoever at the time, and he realized and had to get Aldridge back in the game.
I mean, how dare I question us not having a time out in a game where it would have been useful. Down 3 points, we could have used that time out instead of Steve Blake forcing up that airball...we could have run a play.
We have to second guess Nate's coaching on these types of plays, to ignore it would be idiotic.
