I voted 2nd. I think Toronto is going to finish with 60-62 wins this season so yeah, they will be the 1st seed and probably take it by a good 8-10 game margin.
But the Celtics are currently 6th in the East and just 2.5 games back of MIL/PHI (both tied for 2nd currently). Indiana is missing Oladipo for a while now, and I think DET will start to level out a bit (be more of a 6-8 seed).
Hayward is looking like Hayward again and we seem to be figuring things out. When we start to gel better and become more consistent, I think we can get to the 3 seed maybe in a few weeks and then get to 2. But yeah, TOR will run away with the #1 seed barring a major injury.
