A: It's too early to think about thinning out the perimeter rotation, with Erik Spoelstra still sorting through the possibilities. Plus, Dion will be out for at least another week and a half, and that's only when his injury will be reevaluated. But taking the long view, with Goran Dragic thriving in a ball-dominant role, it only makes sense for Dion to transition back to his anticipated role, as a reserve guard, where the touches will be more plentiful. Keeping Dragic in rhythm is much more important than getting Dion back into a comfort zone. But if you do play Waiters off the bench, minutes still will be an issue, with the need to also find time for Josh Richardson and Tyler Johnson, let alone Wayne Ellington. What the past week showed is that players play well in extended minutes, be it Ellington, Josh McRoberts or even Rodney McGruder. At some point, Spoelstra is going to have to tighten his rotation. And that leaves Waiters' role a question mark.
