Lebron and Rich Paul get their way. If the Lakers can also get Kemba or Kyrie, I think they just became favourites for the next title. It's disappointing for the league that Durant and Thompson are out next season. If they were fit and Durant stayed with the Warriors, that would be an epic Western Finals matchup!
For the Pels, everything depends on Zion living up to the hype. If he does, Ingram and the #4 pick this year could form a decent supporting cast. Will be interesting to see if Holiday wants to stick around. He'd be a good mentor for the young players.
It's disappointing from a Celtics point of view as Davis would have really put them in contention. But the writing has been on the wall for some time that AD had his heart set on the Lakers, so I think Ainge did the right thing in limiting his offer.
The Celtics are still well placed with the 'Jay Team', Hayward, Al and Smart, plus potentially a very good Grizzlies pick next season. They just need some more help at center to take the physical load off Horford. It'd be interesting to see if Vucevic would take a 3-4 year deal for $20-22 mill. As a FA, Boston wouldn't have to give up any assets and he is a very good rebounder and decent outside shooter who would fit Stevens' offence.
