I knew it!!!  When I saw that monster dunk on the last game and it appeared that Griffin grabbed his knee, I knew something was wrong.  Then on the next play, he had a turnover, seeming like he wasn't right.  Then he didn't come out on the last 4 minutes of the game I believe.  Oh man oh man, I hope this is nothing serious!
