Re-signing Splitter is made easier thanks to him being an RFA. The way I see it, McGee's contract is the the absolute max they can expect to have to pay to keep Splitter. Most likely, he'll be getting Asik money. So Splitter at $8 Million a year and Green at $3.65 Million would be almost equal to McGee's contract alone. Getting Green means they don't have to worry about re-signing Brewer, who really could get a big pay raise. So you take away about $5 Million for not having to keep Brewer and you have a savings of almost $4 Million. Even if you have to pay Splitter a ton of money, that still makes you break even. With the wing position secured, they can trade Chandler with no worries about having no one behind Gallo. That could save them even more.
So I do think it can be a smart financial move to send away McGee for players like Splitter and Green. I don't see a better deal out there if the Nuggets don't plan on rebuilding. You add the fact that the team should be better after than deal and there is definitely the possibility that the they end up doing something like this down the road. I don't think they'll consider moving him until next year, though. They still have to figure out their front-court, and they'll probably give everyone another off-season to adjust.
