Gobert is a bonafide All NBA player. In theory, IT was All NBA also. If you take him off the Celtics and get whatever value in return via trade, it's down to Hayward, Horford, a rookie, a future rookie TBD, and enough cap space to sign one more dude. A lot of maneuvering needs to take place. Could Ainge do it? Maybe. But it could also blow up in his face.
Sure, I think Gobert is better than anyone Boston has to help Hayward, but everyone after Rudy isnt as good as Butler/Horford/Fultz. And look at who is winning, it's teams with multiple #1 options. Rudy is great, but he isnt a #1 option. The Boston team they could potentially put together would have 3 #1 options and a playmaking center.
Like I said earlier, I think it comes down to how much Boston has to give up to get Butler or George. If both those teams cave to Boston's position and give it up relatively easy, like just for the 2018 pick/Crowder/Smart, then I think it's hard to look at Boston's situation and not think it's better than Utah's given all the variables.
Lebron will fall off before the Warriors do. I think that is pretty obvious. Do you want to be in the East or West? Even if you think both teams are even, the Eastern conference team has to get the advantage. You get to the Eastern Conference Finals every year at least. Out West it's a potential 7 game series every round.
