Formation/Snapper?

[BigWill]

Team A lines up at the 3yd going for 2 they are in a swinging gate formation the snapper is at the end of the line he is positioned sideways when he snaps the ball is this legal?

The snapper must be a lineman, so his shoulders must be approximately parallel to the goal line. If he lines up "sideways", that's not legal. If he turns sideways prior to "snapping" the ball, that would be a false start. If the "quick continuous motion" of the snap results in him rotating a bit, ending up sideways after the ball is released, that's probably fine, but I'd have to see it.

He can snap sideways but as noted he must be legally positioned and lined up as a lineman.  See rules 2-32-9 and 2-32-14.

Are you saying the snapper's shoulders are perpendicular to the line of scrimmage?  If so, no bueno.
