I was surprised that Doc went with Baby in he 2nd half. Other than some energy plays there towards the end, and decent defense (got to give him that) he was having a very bad game making poor decisions with the ball, and getting stuffed down below constantly.
I thought Sheed should had been inserted when they took Perk out, particularly because they were clogging the middle and Garnett could've used the space.
But it all worked out in the end, I just don't see why Baby was given the chance considering how bad he was playing.
