no brainer that he'd play the 3 in boston.
-we do not need another 4! Kelly, Sully and Bass are already crowding that position, and that's assuming we don't bring back hump.
-the 3 is his natural position size-wise, as he would be slightly short and very skinny for a 4.
-the 3 is his natural position skill-wise too. He has no post game. On the other hand, his faceup game is far more developed due to his handles and passing, and he is an elite perimeter defender. To be a good offensive wing he must add a respectable corner 3 (and hopefully a midrange jumper, too), but he can be average just based on transition, slashing, handling, passing, finishing.
Watching Kawhi Leonard is making me more enthusiastic about Gordon. He brings enormous value in a series against LeBron. Gordon can easily be as good as Kawhi if his shot develops better than expected.
