We don't have a big who can score anyway, so upgrading the defense of one of them doesn't hurt the offense any. It's still a net positive.
Doesn't really matter to me anyway, Noel would be just fine running a P&R offense with Kemba. If it's determined that he's the BPA when we pick, then I don't want that to mean we give up on Bis. Let them play together and figure it out. We can still add a scoring post player with the Portland pick or from the FA market
