These contracts are exactly why trading for players on longer, tream friendly deal is worth giving up some extra assets compared to getting players who would need to be extended in a year for a bit less.
Denver really ed themselves with that MPJ contract.
KCP is most likely gone and even after dumping Reggie and scrubs, they're still around 30M over the cap.
Murray also entering his final year, just got a 209/4 extension.
The only way out is to trade MPJ for depth.
Also, there are some rumors of them being interested in PG13 in S&T deal. That would be a definite short-term all-in play.
