NERLENS!!!!!dallas would probably ask for that lakers/kings pick which i'm sure danny would not give
Nerlens can and will veto any trade.
Not sure he would Veto a trade to a young Celtics team with this much upside. It's hard to envision a better scenario for him then a team that has Kyrie (25), Brown (20), Tatum (19) and Hayward (27) as a young core for the future - he'd fit right in not only now, but for the foreseeable future too.
Throw in the fact that we have Al Horford - who's offensive minded skillset is a perfect compliment to Noel, who's experience makes him the perfect short term mentor for Noel, and who's career path also matches up perfect (as Noel develops, Horford is fading off).
Then on top of that you have Brad Stevens as a coach he could learn tons from, and Danny Ainge - the GM who will stop at nothing to add talent and build a winner.
Or he can stay in Dallas, and wait for Dirk to retire and for the team to become entirely irrelevant as a result, and go through another rebuild nightmare just like what he suffered in Philly.
I know what I'd do.
