I am very curious about this, especially since the Patriots technically *didn’t* commit any 5-yard pre-snap penalties.
They didn’t throw a 15 yarder against the Squealers that time they kept going offsides to block that FG, although they were on defense at the time so maybe that’s the key difference.
But yes, this is something which I’ve noticed in the past, especially in the college game, and I’ve always wondered if some coach out there would have the nerve to exploit it by, say, running (for example) 8 minutes off the clock between plays (or forcing the other team to call a time out)
