I mean, they pretty much shared the same qualities that all great wrestlers do. Just in different quantities.
They both had good technique, Smith was known for it, but I think Brands' was definitely underrated.
Both guys had great gas tanks, they'd stay on guys the whole time out there, Brands was the guy more known for that but I've seen a lot of
John Smith matches and I've never seen that dude get tired.
Brands was also known as the physical/grinder guy, but again I think Smith's attributes here are pretty underrated too. He was a good handfighter when he had to, and he finished his singles quickly, and at times pretty brutally.
If you haven't seen it, we have a video on another section of the board from 91 US Nationals of Smith at his apex absolutely woodshedding a just finished his junior year of college Brands.
