Rex Ryan: Did He Know About the Wall?

New York Jets assistant coach Sal Alosi was suspended for tripping a Miami Dolphins player as the athlete ran near the Jets bench during a game. Alosi was later discovered to have been behind the idea of constructing a human wall along the sideline, with the purpose of diverting the attention of opponents during punt returns. A legal but shady move, the question remains whether Jets coach Rex Ryan knew about the wall. Ryan claims he wasn't aware of such instructions coming from Alosi, but what kind of coach wouldn't notice his players lined up toe to toe during a game?
