Faried's not nearly so quirky as you make him out to be. He's a 6'8'' physical freak who finished off the season reeling off 20 and 10 games on 60% shooting. Of course, those games were meaningless, but the point is that the talent is there. He's got the physical makeup of a star wing player but has no perimeter game.
He's not a perfect fit in pretty much any offense, but he's got too much ability and he's too productive to not find a great situation somewhere.
I mean, the Celtics got killed in the Cavs series by Tristan Thompson (who is only an inch taller) because they had nobody with that kind of freakish athletic ability to gobble up boards on both ends. Faried's not a prototypical big guy, but he's not some oddity.
