Pittsburgh just had to play without their kicker for a half. They just end up managing the game to not count on the kicking game and won it, it's not the end of the world. And I thought belicheck was specifically addressing the backup qb as the player holding since that was the majority of the players who did it back then. I think it makes for an interesting fake scenario if you have jones or even Mckenzie holding because if they take off with the ball they would be tough to catch before turning upfield. The kick block team would have to account for that and either not rush that side or keep their safety player shaded to cover the holder taking off.
