Brock- all of his accomplishments from winning titles to beating the streak. His first run is legendary and I'm pretty sure when we look back after he retires we will admit we enjoyed his second run as well from the lesnar vs punk lesnar vs aj lesnar vs goldberg lesnar vs cena vs Seth his feud with taker his recent main event at summer slam. He's a one or a kind freak of nature where he's that large but can move fast AF. He went to ufc and was a draw there and actually won matches.
Only real negative is you can bring up he could be bigger or a lot more important to wrestling history if he stopped milking this part time shyt n milking the wrestling world putting little to no effort in most matches now. But even then he's always gonna be one of the top guys of all time and one of the most recognized names when it comes to wrestling in general.
So the fact that he could be greater if he cared says something.
Goldberg- the only reason why I'm putting him over batista, even though I prefer Batista over Goldberg, is because he was like the biggest draw for wcw besides nwo during the Monday night wars of the height of wrestling.
Batista- even tho he's last he's still pretty damn important and successful. It just happens these other guys are a lot more successful in some way.
