I don't know how the Bucks would feel about trading away KPJ but the idea is that they get a better athlete and all-round defender that can guard all positions, as well as a way better floor spacer (Only concern would be his health)
The Nuggets get a healthier defender but the main highlight is they get a better ball handler and perimeter defender in KPJ, that can alleviate Jamal Murray off some guard duties.
The idea I have in mind is that the Bucks have too many guards (Especially if they plan to keep Herro and Caris Levert), so maybe they'll be more open to letting KPJ go also considering that's he on an expiring contract π€·πΏββοΈ
Let me know if the Bucks need some extra assets or vice-versa π
