No he is actually 3rd in offensive rebounding and 4th overall in rebounding. So 88 offensive is pretty good imo.
I don't think he is worthy of 90+ for offensive rebounding.. if you put his putback tendency up like I did then he will also try and get in better position for putbacks which will lead to better positioning for some extra rebounds.
Some of the moves that I changed are to make him look more authentic on the court... he has shown that he can handle the ball fairly well and he has also made some unorthodox shots down low as well.
Don't knock my BGriff till you have played him.
