Completely different dynamics between Rose/Howard and Griffin.
Rose and Griffin have been in the NBA awhile and are used to the big minutes and the NBA schedule.  I see neither, in their youth, burning out anytime soon.  We could hope..lol..But it isn't going to happen.
Griffin comes off an injury where he couldn't walk.  I can't imagine the work it takes to have the cardio it takes to play one NBA game.  Let alone 82.  It's amazing, at the pace Griffin plays, that he didn't hit a wall 10 games in.
