I think both Brown and Tatum have a shot at making an all NBA second team (I don't think they both will, but think one of them has a legit shot). Most thought Brown should have been a starter for all-star game. Do people think neither of them could? Or is this not how we determine top 10 players.
After a hot start Brown has cooled off a bit. He'll make the All Star game because he has shown enough this season and he's on the Celtics, which helps for your reputation.
Brown and Tatum are really good, but there are a ton of other guys who also play lights out. I don't think Brown has a shot at All NBA unless he goes "Tatum like February '20 nuclear".
Currently I assume (9): Curry, Lillard, Doncic, James, Leonard, Durant, Antetokounmpo, Jokic and Embiid as locks.
Likely picks (6): Irving, Harden, Beal, George, Davis, Gobert
Other candidates (7): Young, Mitchell, Butler, Tatum, Simmons, Sabonis, Vucevic
(that's 22 names before Brown, Adebayo, LaVine, Williamson or Randle comes in the ball park)
