The taping from the endzone is not legal if the cameraman is still accessible, in-game, to the coaching staff.
Your contradicting your buddy fixit, so you're allowed to tape from the endzones as long as the coaches don't see the tape. Makes sense to me, this would seem like a coaching purpose. Break down the plays, tendencies, etc. Alot diffierent than knowing exactly what plays are coming. Come on guys, you're calling me biased but if the shoe was on the other foot you would be pissed that the Jets knew exactly what play was coming before it did.
