Presently sitting at 35-19. I'm thinking we go 16-12 the rest of the way and end at 51-31.
Looking ahead to next year, we know we'll have PP, KG, Perk, Rondo, Sheed, and Baby on board. Who knows what will happen with Ray. Maybe we resign him using Bird rights, maybe not. Other than that, all we have to try to improve is the MLE. Yeah, we'll have a first rounder, but I'm not expecting big contributions from a late first round rookie. I anticipate further slippage from the core old guys (whether that includes Ray or not).
I'm guessing we'll fall into mediocrity next year at around 44-38, and there will be much chatter around next year's trade deadline about whether to trade PP or not.
Edit: Oops. There I go attempting math.

Fixed.
