If Charlotte is willing to do a deal centered around Green and MKG (I'm assuming they want to contend this year) then we should jump at it.
Call me crazy but I think MKG is going to be Paul George down the road. I just see it in his young, awkwardly developing game. Plus he's a great athlete.
Plus he's a leader and an extremely hard worker. That's what ultimately makes guys like that guys you can build around.
I like MKG for a number of the reasons you mention, but I don't think the Paul George comparison is fair, certainly on the offensive end. He's not a guy you can build around -- he's a solid role player as a defender, essentially.
But, I also like Jeff Taylor. A lot. He was absolutely outstanding in the FIBA Euros last summer. When he returns from injury, he needs a chance to develop in a different role with a different team. But he's always played behind MKG while Michael's tried to prove his worth as a Top 5 pick (unsuccessfully).
Also keep in mind two things I mentioned in the OP:
1) JT makes less than $1mil next year (MKG makes more than $5mil), and more importantly,
2) Chances Jordan does the deal with MKG in it are considerably slimmer, IMO.
