Denver probably do not want to pay KCP 20mil a year when Christian Braun will be ready to start in the s.g position the following season. Bobby portis can help relieve some of jokers responsibility, keeping him fresh for playoffs. Portis can also play PF, and help with the shooting spacing
The bucks will need a high level 3-D shooting guard that will help cover lillard's defensive flaws. Can sort of fill the hole the jrue left.
They will now have one of the best starting lineups in the league with:
Lillard
KCP
Khris
Giannis
Brook Lopez
