I'd also like to see Tatum shoot the ball better, but what's frustrating about the Tatum discussion is he's doing the things we've always said we needed him to do in order for the team to win a title, but because his three point shot isn't falling, it's getting lost a bit (not entirely, but in some cases).
We know Tatum can score the ball, he's always been able to. What he hasn't been able to do, in the playoffs, is react to how defenses are playing him, and not just make the right read/pass, but be able to manipulate the defense. He's doing that now. Teams try to trap him, and he's not just passing out of the double, he's making the incisive pass that breaks down the defense based on how they're playing him. He's passing in anticipation of the second defensive rotation, not just the first. And he's doing it without turning the ball over. This is elite level decision making. I didn't see it as much in game 1 against Cleveland, but Miami mortgaged the series on the idea that Tatum couldn't do what he did.
Part of it is that the cast around him is better; the level of shooting around him makes the process easier. But Tatum has become a real playmaker rather than a guy that just shares the ball. That's the last level for him in terms of carrying a team to a championship. He's now a guy that makes the guys around him better. And he comes out every game looking to draw attention and move the ball. I wish his shot was falling too, but he'll get there, especially as teams realize they can't overload to him the way they have in the past.
