Jae Crowder is a defensive specialist. What makes him even more special is his contract, very team friendly. But, having watched him play last 2 seasons, he takes a lot of terrible shots. If he can fix that mental issue he will fit in great with the cavs and would be a great asset. Celtics were never going to win with Thomas, he can't defend anyone. That was displayed last season in conference finals as Irving destroyed him.
I'm real excited to see Irving work with Brad Stevens. Could be a special year for him.
