Here's my stance on the draft:
Embiid is great if he's healthy and available when the C's draft, but if he isn't (and I believe he won't be), I'm loudly beating the Exum drum. He's got height, foot-speed, range, the ability to create his own shot, and above all else, serious maturity. From what I've seen of this kid, both in game film and interviews, he has the IQ and desire to learn high-end defense. Drafting him also bids farewell to AB, who I love, but has no future next to Rondo.
Exum's gone when the C's draft? It's Gordon time. AG with Rondo would work itself out offensively, and the kid is a defensive beast. Great building-block with monster upside.
All that said, assuming Embiid is in fact gone on draft night, here's an idea for centers:
http://espn.go.com/nba/tradeMachine?tradeId=pj2mgrjBoston gets:
Gorgui Dieng, Timofey Mozgov, Nate Robinson
Denver gets:
Chase Budinger
J.J. Barea
Minnesota gets:
Jeff Green
Phil Pressey
DEN second round pick
BOS two second rounders when Philly misses the playoffs in '15
Dieng is a dynamic young center to build around, and Mozgov is underrated and poorly utilized in Denver - this would offer two strings of solid rim-protection and allow Sully and Olynyk to shift back to their natural positions. I'd even consider giving up a protected first-rounder to make this happen.
The Green experiment failed, and he has no future in Boston. Minny will go for a win-now attempt before they have to concede and trade Love, and Green starting as a third of fourth option would help them achieve that.
I expect Ainge to trade for or sign an all-star SF - that's where the fireworks begin...
