Sending Macklin, to the D-League, might not have been a bad move for him. Giving him time to work on his low post game, and to gain some experience would be good. He needs time to play, and gain confidence in his game. Mental reps are fine, but, nothing takes the place of good ole floor time. He will return better, and break into the rotation this year. And, make a big push for more playing time, if not, a starting position, with a good off season next year.
