Walker definitely grabbed the ref and moved him back to get the ref out from between he and O'Neal, and that's a definite no-no. If Peja can get suspended for putting his hand on an official's arm to try to slow him down, Walker definitely has to get suspended for a game. Stupid move by Walker in this context, as he should've known that game 3 was lost, and there was no reason to continue on with the rant at that point. His absence could definitely hurt the Celtics, although Al Jefferson has been doing quite well (at least according to the Sports Guy) in the time he has been on the floor since Indiana has been running James Jones at the PF spot with O'Neal at the C. Celtics may in fact benefit from some increased time for Jefferson.
