KG and doc were more shocked that gibson's arm rake wasn't a foul I think, KG even turned to the ref on the TV telecast to ask if it was a foul and pointed to his arm.
Gibson was trying to strip him as he caught the ball, and generally be a pest since he knew it would be nigh imposable to get a shot off after having to catch an inbounds, but it looked like he got alot of arm, but i think the ref was hesitant to call a foul when chances are KG couldn't get the shot off anyway.
Doc then pulled the official aside and asked him about the reach in, and it looked like the official kind of blew him off.
im with the ref, not a foul i would call either, it would have givin up some pretty cheap FT's. As a celtics fan i would have liked it called, as a basketball fan i wouldn't have.
