Insane or not?
Mozgov is and definitely very underrated... But the value of Sullinger is 4x more greater in value, regardless of his back injuries. Mozgov is 27, and still looks like he struggles on offense. Sullinger looks like a promising young player, who despite his back issues, looks like one of our most prized asset... So why trade it away for a Center that was struggling to find time?
I agree. To me, Mozgov is the sort of player that isn't hard to acquire in free agency. He's a decent player, but it doesn't make sense to give up significant assets for him. You only go out of your way to acquire a player like that if you think he has a lot of upside given a change of scenery and coaching philosophy.
I don't think that's in play with Mozgov. He's a borderline starter and a capable backup. He doesn't have any skills that really stand out. He's a 7 foot, 250 lb body with some basketball skills. Period.
Sullinger is young, and though he plays a position that is very well stocked on this team, he is not the sort of player that is easy to acquire. He may or may not be a long term fixture for this team, but it doesn't make sense to give him up unless it's part of a deal that gets us a likely long term fixture in return.
