The number of players that can finish with both hands in college consistently is miniscule. That is one of the consequences of the AAU circuit.
I think people notice it more with Fair because he is a lefty and it looks weird. I mean, could anyone on Syracuse's team this year finish with both hands consistently? I didn't see Triche or MCW initiate many dribble drives where they would have had to finish with the left hand.
Now yea, if he could do improve it, that would be great. I just think it would be easier for him to get the confidence in his 3 pointer and have it game ready for next season then learning how to use his off hand.
