No, but the movement has to be something that he would do on the snap of the ball. In other words, the movement causes the TE to move as if he thought the ball was snapped. People are really saying, the TE was set (in a two pt. stance), and he can't reset? Have you watched how many times a game our TEs, both on and off the LOS shift and reset?
Standing upright and pointing at a guy in the neutral zone isn't that. Nowadays there is so much shifting/resetting, standing up to look at the sideline for a playcall or change, and pointing out protection/blitzes, they aren't going to call that sort of thing.
******** about the offsides/non-offsides call is dumb to me. First, if there's no contact, the ball isn't snapped, and the description of movement by the offensive players doesn't necessarily fit the description of a false start.
Second, even if it was, Purdy gets a big gain and a first down on the next play, so it literally had zero impact on the game at all.
I've seen numerous time that Soehner has been set in a 2 point stance and flinched then gets flagged for a false start. What's your point?
