Ok, so now we're looking at tapes of the Dolphins' offense from a game in an Oct. 7, 2001 game.
On one signal, the Miami offensive assistant is on the sidelines with his hands out, as if he's an umpire making the "safe" sign. That's it.
On another, he pumps his right fist three times and then touches his shoulder. He repeast the motion.
On another, he waves his hand over his head three or four times and then waved his hand in front of his face. He repeated it.
