Miller is a good player, but if he's complaining about his role in Portland and is becoming a locker room distraction, why would it be different here?
Exactly. It'd probably be far worse here, where he'd be lucky to find 15 mpg.
Plus, while Miller would certainly be a talent upgrade, too much is being made of the backup PG spot here. Sure, Eddie House isn't Rondo, but no one we get will be. Plus, we're talking about 15 mpg or so during the regular season, and probably closer to 5-10 mpg come the playoffs. Who really cares?
