The "sudden movement" offsides call

[MountaineerWV]

Would have resulted in a 1st down. Perhaps leading to go-ahead touchdown. But I ask, how come that is offsides on the offense? The lineman did exactly everything legally allowed. The offense is allowed to send people in "sudden motion". The defense is allowed to have "sudden motion" (as long as they don't cross the neutral zone).

Silly penalty that makes no sense.

Was a bad call but would it have mattered? We will never know.
