NFL: ***2026 NFL Season***

I don’t understand that call at all. If the offensive players are moving, isn’t that an illegal procedure and dead ball? They certainly were never set, so how do you have an illegal shift if they weren’t set in the first place?
 
Refs wanted the Chiefs to win so they call illegal formation instead. Can't make it up how they "luck" their way to wins.
I'm at my in laws so the game was on but no audio. Didn't realize that was the call.
