First of all, the tactic is to force the gunner out of bounds, so the rules therefore allow the gunner to return to the field of play. There's nothing illegal about being forced out and returning into the field of play. The purpose of the "wall" is clearly to intimidate the gunner by making him worry about the possibility of injury when running the resulting gauntlet -- as explicitly shown by Wall Coach Alosi himself. It's unbelievably egregious for the very coach responsible for organizing The Wall to personally demonstrate that the intent is to intimidate to the point of injury. The practice squad players making up The Wall weren't being "dinks", they were following their coaching.
But the Jets *were* indeed also breaking a positional rule by having inactive players in the area of that wall. Only coaches and players eligible for substitution are allowed to stand within 6 feet of the "Chain Crew and Officials only" 6 foot white strip:
So the Jets coached having players in an illegal location. The Patriots coached taking videos in an illegal location. Belichick took personal responsibility for the positional violation, and he, the franchise, and the fan base have suffered mightily for it. The Jets, instead, are attempting to evade organizational responsibility and instead scapegoating Alosi. And it was the Jets who turned the Patriots in for the video location violation, even while engaging in the same practice themselves. Damn right I want to see the Jets suffer. Karma is a b*tch.
