He passed up a couple early in the game where he was wide open and you could tell he thought twice about it. After that he did not seem to hesitate. I wonder if Terry told him not to hesitate. As Blue9 pointed out a couple were against the shot clock (one was Plumlee's fault) but I agree if he is going to shoot them he needs to only do it from where he shoots the best percentage. I think you are right about it being in the corner.
As for Harkless, I think he took a 1000 three's a day last summer, but I agree he needs to keep at it. His form at least looks good, so I am holding out hope. But to be honest he does not seem to have a mid range game either, so until he adds something other than a dunk to his repertoire, his minutes will continue to be inconsistent with Terry. But I love his hustle points, it is something we have lacked for a while.
