At the risk of taking this thread too seriously, I see two separate but related questions here:
1. Is Tatum a true #1 (Batman) or can he become one?
2. Not explicitly said but the other question if Tatum is better without Brown?
I think this game threw cold water on either of these. Clearly, Tatum can be a top dog on a good team. At age 23, he doesn't do it every night but he has done it enough that it should be pretty clear that he is really really good.
The other question, Brown and Tatum together, was also illustrated in this game. Again, they don't "click" every game, every quarter, every possession, but the game last night showed that if they play the right way individually, if the team as a whole plays the right way, and everyone plays with urgency, that Tatum and Brown can play together and play really well together.
