So since KD left:
Durant - Fit in seamlessly with a historically great team, dominated the playoffs, won a championship & Finals MVP, took a huge pay cut to help keep the team together
Westbrook - Took a million shots as a one man show, won MVP, lost in the first round, got his GM to make desperation trades to get one year rentals of P.G. and Melo, then signed a $200 million extension; will likely never win a title but will likely make substantially more money over his career than KD.
Seems about right.
I'm happy for OKC fans though. These days it feels more and more rare for one player to stay with a team long term and to have that security as a fan to know your team will have a consistent core identity.
