I can't believe anyone could seriously think the L didn't give a signal. He blows his whistle and is sliding/hopping to his side while holding two fists high in the air. Let's not kid anyone here. That's enough for everyone to know he's calling a block.

Question for those trying to tell us the L didn't actually signal: in your opinion, at what point is the block signal actually made? Is it once the fists start to come down? When they actually hit the hips? Somewhere in between??

I agree with Camron. The signal was received, which means it was sent.
