I'd do Crabbe straight up for Noel. Noel is a difference maker on the defensive end. I'd prefer a two-way big like Anthony Davis or Al Horford, but how many of those are there and how likely are we to get one? Next best woould be a defensive stopper and Noel is that, young and available.
Just thinking, if BOS doesn't meet expectations, they may want Turner back - even that his inflated salary. Why spend all that money on Horford and underachieve? But, that's a huge assumption as BOS, like us, is 2-1. They aren't exactly dominating anyone (5-point win over BRK, 6 point win over CHO and 6 point loss to CHI), but also, like us, they are trying to integrate a new player into an established rotation.
