McCabe is 40% from three this year and is second only to Clemmons in 3PT%. McCabe was 45% last year. I'd say he's been pretty consistent.
It isn't just about shooting percentage with McCabe though, he attempts just under 3 threes a game, so he isn't really a threat, despite shooting a good percentage.
Hard to justify starting a defensive liability because he makes about one three-point basket per game.
I voted Basabe. I am actually a McCabe fan, I love his energy, but it may be better suited coming off the bench. At least until he can consistantly knock down open 3's
