Rex Ryan said he had no idea that inactive players had formed a wall on the sideline -- even though a TV replay shows him standing right there.

Special teams coordinator Mike Westhoff also maintained that he had no knowledge of a wall -- even though he was standing right there.

Former Baltimore Ravens coach Brian Billick, Ryan's old boss, begs to differ.

"Of course Rex knew about this," Billick, an NFL of FOX analyst, said Thursday on ESPN's "Mike and Mike in the Morning" radio show. "Players crowding the sideline, a gunner running down the sideline, has always been an issue, and I think what you're going to see with the league is the proverbial, 'We have a rule in place, it is going to be enforced.'"

This, of course, is part of the fallout from the Sal Alosi tripping incident. Alosi tripped a Miami Dolphins gunner, Nolan Carroll, and, after a three-day delay, the Jets announced that Alosi instructed five inactive players to form an illegal wall on the boundary. Alosi was suspended indefinitely.

The Jets claim Alosi wasn't coached to do that, that he acted alone. The team is investigating. The league is investigating if the organization is culpable and whether Westhoff crossed the line by public accusing the New England Patriots of the same tactic.
