Problem was, it was hard to get a smart cat that was that big. They happened, but not all of the time. I remember right before I moved out here we got a division one quarterback from like New Mexico or New Mexico State or somewhere in the Southwest who had made it through RASP. I thought to myself... This dudes a quarterback, he may be the first really smart 240 gunner in the history of the Ranger Regiment... so I pulled a Jon Gruden and asked him to give me a play call. I was like, "Say we were in the huddle, and I told you to run some kind of wide reciever screen, what would you tell me?" I don't know if it was nerves or if he was being honest or what, but he was like "Gun right, wide reciever screen." I started laughing and was like "Are you being some kind of a smart ass or were you not a quarterback?" No, he was really a quarterback, showed me pics online and everything, but that's where we are these days.
But I digress. To your point, yes, it's normally the big Ox that gets that job and typically that Ox needs to be trained all day every other day. If that Ox misses a training session, he forgets everything you've already taught him, lol.
Good times, thanks for bringing that up, I'd almost forgotten that story.
