I think Cousins would do well here because he's talented. A winning environment would definitely help his image too. I don't think he'd change much but honestly, look at a guy like Draymond Green. Because the Warriors are winning, he's called passionate. But if he was on the Kings kicking people in their Christmas ornaments, he'd be called a thug and a head case.
If we keep most of this team intact and get boogie for a package like Rozier, Amir, and some valuable picks, we'll be contending with a very bright future.
