He don't need to say that because Jimmy Butler and anyone else who's followed the NBA know how Melo and Dwight tenure in the league ended.
BECAUSE HES SPEAKING UP
FOR THE "ORGANIZATION"...
HES NOT SAYING
"I MADE THE SAME MISTAKES, ETC"
HES READY TO BECOME
A COMPANY MAN AND IS AUDITIONING
FOR THE NBA JOB
Why wouldn't Melo be genuine in what he's saying to dude? You can call it ready to become a company man, but it sounds like maturity because both Dwight and Melo know how this can end for Jimmy.
