If the Lakers were willing to give up 3 firsts, and the Suns were willing to take Ball for Bridges, and I could find another taker for Ingram, I think I'd do it if I were NO. You'd have a ton of cap space, and (ideally) post-Lebron era picks to play with. The downside is that you need to flip Ball, and Ingram blows.
It sounds like the Celtics would offer Tatum, and they have picks this year, but only the Sacramento one and the Clippers one get you in the Zion lottery, and barely at that. You could get Rozier too, I guess. It's wild that Ainge is willing to gamble on Davis staying.
