it is a call that has been made by centers since before Brady was born
Ahem.....Brady was not born. He was forged in the fires of olympus from the blood of Zeus, bequeathed on mankind to deliver us from suffering by displaying football skill unknown but among the gods and envied by the universe. Women want him, men want to be him and all yearn to be in his presense. His eyes illuminate the darkness, his sweat cures disease and his very breath gives life to the cursed earth.
it is the player who is the "free man" in the blocking scheme ... so either the center, pass protecting back, or TE need to pick him up should he be not dropping into coverage
in laymens terms ... he is basically the unaccounted for man in the O lines blocking scheme for that particular play.....
sometimes saying....55 is the mike.... is just like saying .... hey FB 55 is your responsibility
I thought the Mike was always the second "LB" off the weakside (regardless of the player's actual position)? So in other words if a safety steps into the box at the WIL, then the WIL then becomes the Mike.
