GL Jeff nailed it on the rules. The replay Singgles showed didn't show enough info to call, but one they replayed clearly showed the first one no hands on the ground and the 2nd one his hand was close if not on the ground at the time of the strike. The reason Ross was putting his hand down will always be speculation, but when the knee started no hands were on the ground. In the end we get to see it again. The ref had to make a split second call and replays and the rules backed it as his call
