They review spots of the ball all the time. I have not gone back to review the replays, but I thought the official in question came in pointing down to the ground which is the universal down by contact motion, which is reviewable. What ticks me off is when they talk out of both sides of their mouth regrading let the game play out and fix it with replay. I think the rule that needs to be visited on this play was the INADVERTENT WHISTLE rule, pretty sure it is still in the book somewhere. He was clearly never down and was fighting inch by inch while being pulled by our OL. Hiding behind a judgement ruling, is pretty weak. Advancement of the ball and spot is replayed all the time.
They had to get together and make some rules changes after our last game ending call in this game. MIght need to meet again.
