Right now PHI and MIL in the East. Obviously TOR if Kawhi returns.
But the West is wide open. Will be interesting to see how good Curry/Draymond/Kerr really are.
I'm sure Houston likes to think they're next up, but they didn't play all that great last year, rumored turmoil, and have done nothing to improve, I'd be surprised if they break 55 wins or get past the 2nd round. They can beat GS finally, but I don't think they can beat everybody else out West.
Similar story with the Lakers, I'm sure they like to think they're next up with LeBron and AD, but so far have a real lack of depth. AD's no iron man, and LeBron finally showed signs of being human last year missing 27 games. LeBron might actually start to decline, maybe have some real injuries that slow him down, or maybe LeBron having 8 months off for the first time in 15 years comes in rejuvenated and has one more monster MVP season giving a big middle finger to all the doubters. Things could go great in LA or it could be a disaster.
DEN, POR, UTA all have potential to take the West. I think we've seen the best OKC can offer (and it's nothing special) but with the right matchups who knows. LAC if they land Kawhi probably go to the top of my West.
But for once, if Kawhi stays in TOR, I could see the top 3 teams (in terms of championship potential) being in the East, for the first time in a long time.
