I believe the Celtics need to try and move some pieces to get Bagley...aka Bosh. They will need a big man that can shoot to combat Embiid for the next 5 years.
Brown, Rozier and Kings pick could get it done.
We get a rookie contract and unload two potential bigger contracts while maintaining a good core. Money will become an issue...get it out the way now while stock is high.
Believe and need are completely two different thought patterns. Also Bagley is rail skinny, I'm A HUGE supporter of him. But I'm thoroughly convinced his actual position will be a 4, and even if Brad Stevens doesn't have set positions. That is mainly what Bagley is going to end up doing anyways.
That being said, Bagley is a great talent, and I have no doubt his height, motor, mixed in with his hustle play will be a fan favorite in Boston. But no way in hell is he worth Brown, Kings pick, and Rozier..
I would do Rozier+Kings pick max.
