As pleased with the coaching as I am, this is the kind of 'out of the box thinking' that would suprise me under McD.
I feel like Allen might do this.
I thought this about the drawing Offside thing, they look like they are going to not snap it so why not snap it and take the opponent off guard, every opponent would be wary then and may need to burn timeouts not being sure if the bills will snap it on 4th down.
