Insert all the caveats about Butler being a great player here.
That being said, who exactly can Butler play with and who can he play for? Given his tenure in Minnesota, I don't think he can play with the young rosters that are the Nets and the Knicks. I think he can play with the current Clipper roster but if Kawhi goes to the Clippers, can those two work together as both seemed to want to be the top dog? Same for if Kyie/KD goes to the Knicks.
What is his perfect situation?
I introduce to you the 2018-2019 NBA champion, Jeremy Lin!
