Although, I don't think it is so much Woodson's call as the players adjusting, especially Melo holding the ball and calling for it in ISO much less.
Woodson f'd up the SG spot by basically awarding it to JR before he even played a single minute. Then committing minutes to him, especially in crunch time, even when he was struggling severely. Never pulling him for poor performances until the last couple of games.
Woodson should have allowed JR to play small minutes off the bench and ease his way back into the rotation. Let JR show that he was back and 100%. I think by committing to JR as the starter in preseason (because that's what he seemed intent on doing) it was bad for Woodson, bad for JR, bad for Iman and ultimately very bad for the team.
Hopefully Woodson will continue to cut JR's minutes if he is not performing and that lights a fire under JR to return to the form he had last year.
Better late than never, I guess.
