He's a bit underrated in the ring, imo. I don't think he has classic matches or anything, but he had that solid Southern territory worker feel to him, no doubt from being in the Armstrong family and getting his training in that style before heading off to the military. For a dude that wasn't a good athlete and had a shytty physique, he was pretty good in the ring in a way that only Southern wrasslers can pull off.
Could really talk that shyt when he wasn't just spouting catch phrases. I'd go with a 6, as an above average talent.
