I hope you are trolling, makes wonder if you are actually watching the games. Both Ibaka and Adams are having big contributions in the series, we cannot say the same about Kanter...actually, he was awful the last game. +6? Again, you must interpret the stat correctly as it could be greatly misleading. You can have a '+' plus-minus despite playing terrible bball. For instance, if you happen to be in scoring run pushed by your teammates. The opposite could also happen, a '-' plus-minus while playing great defense and offense but you might be stuck with a second unit full of scrubs. Plus-minus is a tricky indicator influenced by team play and shouldn't be used lightly to highlight/criticize individual play, especially with a small sample size and no play to actually support your argument. BTW, 9 min is not the ideal contribution you expect from a Max player but Donovan is smart as you said and he realizes he shouldn't play Kanter more minutes than Adams or Ibaka.
