Draymond benefits the most by Durant not being on the court. Allows him to really take over as frontcourt leader, defender, rebounder, point forward leading the break etc.
I really believe KD's injury and Warriors success to date since then (not saying they'd beat Bucks w/o him) have made it much more likely that KD leaves this summer - hopefully to Knicks.
Glad to hear that Mullin looks well and appears happy back on west coast. Change was clearly best for him and for St. John's.
