Well, if LA also threw in their 1st rounder, I think it totally makes sense. The Pacers get some cap relief and some bigs who can at least play, as well as 2 1st round draft picks - their own, assuming they still have it, which will be very high, and LA's. O'Neal's not sticking around much longer, and they're not going to be very good even with him.
The Lakers pick with Lamar/Jermaine/Kobe on the roster isn't gonna be very high, no where near high enough to merit trading Jermaine O'Neal for cap relief.
I know Utah loves Millsap, so this could be an issue, but I think Utah has the money for it (I believe all their top guys are locked up, plus they had almost as much invested in AK47 for a similar time frame), and Marion would be a great fit in Utah next to Deron Williams, Boozer, and Okur. Maybe another player from Indiana or LA gets shipped to Utah in this scenario, as well, to compensate for the loss of Millsap.
I don't see why Marion would be a good fit. He's played in uptempo systems his whole career and everyone know he scores best in transition and in the flow of a game. I don't think a grind it out half court team like the Jazz would fit his style at all. He'd still be an asset defensively, but trading your "diamond in the rough" in Millsap and arguably your best player in Kirilenko for a guy who's abilities don't suit your team (and he's wanting a $60 million extension) doesn't make any sense to me.
