I think the Celtics get 3 all stars by virtue of having a great record and playing team ball. The 3 vets will get the spot because "Brown and Tatum will have their chances" thinking.
Don't forget Blake Griffin is in the East now. The Raptors will be one of the top 3 teams in the East, so they'll get at least 1 and my bet is Derozan. Porzingis will miss too much injury time at the start of the year.
