Others have raised the point that maybe Kyrie is just an exceptional Robin and not an ideal Batman. If that's so, and if Tatum is having a harder time growing in an environment with Kyrie being Kyrie, then maybe the AD trade really is the cure-all. Tatum flourishes elsewhere (good for him), and the Celtics get AD to be Batman while Kyrie gets to go back to being all-world, elite-level Robin. Moreover, AD is probably the ideal defender on a guy like Giannis. AD is basically the same size as Giannis (AD: 6'10", 253, Giannis: 6'11", 242), and unlike most bigs, has terrific quickness himself. Plus he's an elite shot-blocker. Might be the perfect antidote for Giannis, who is obviously going to be a major problem for Boston for years to come.
