http://espn.go.com/nba/story/_/id/10515574/kendrick-perkins-oklahoma-city-thunder-surgery-6-weeks Perkins hasn't done much, but he's a big body down low who seems to play a bigger role than his stats would suggest. My guess is they'll start Adams and this will mean more playing time for Collison.
They usually do when a non-Durant starter goes down. They are succeeding despite their General Manager.
