Brock would win but majority of wrestlers in history would get beat by prime Nash in fight, and im saying that because it's true and also because it will annoy OP who doesn't want people to put Nash over
"Going back to tough guys, one of the last tough guys in the business that I can think of is Kevin Nash. You never saw anybody pick on Kevin Nash. The Steiners didn't do anything to him. Nobody did. Kevin Nash is a tough kid too." - Ric Flair

https://youtu.be/eodsZ3AX5VQ?t=301Things We Learned From Scott Steiner: Live & Uncensored tour at The Garage in Islington, London. Scott Steiner has a reputation for being one of the toughest & most intimidating professional wrestlers the business has ever seen. But is there anybody out there that Steiner himself actually feared? Asked whether there was someone who he would think twice about before meeting in the parking lot for a brawl, Steiner said there wasn't one. Sure, there were tough guys in every locker room he was ever in, but nobody he would be scared to fight. The Big Bad Booty Daddy did name-drop Haku/Meng as someone who was known for his toughness & also said that Kevin Nash would be a tough fight, given his size & experience as a bouncer, but Steiner didn't say whether they'd be able to take him or not.
