There was a great analysis about how overrated Love's rebounds are and how underrated Dirk is in that area. Too bad i can't find it anymore
Bottom line, when it counts Dirk gets the rebound. Dirk also creates space for his teammates and makes rebounding easier. Love on the other hand just tries to grab the ball (long rebounds) and does not care about his teammates. Which is not always good. One should also not forget how bad MIN FG % is. There are simply much more opportunities to get a rebound on offense. Esp. if you play 39min.
Love needs to produce wins, not stats.
