Shawn Michaels was ok, probably one of the better small guys that made it believable that he could beat the bigger guys.
Triple H is probably top 10 for me and he is a great heel.
CM Punk... I never saw much of Punk, I was pretty much done with wrestling by then. But from what I have seen of him, I wasn't impressed. He could never get over on me, he was a small guy, but I never felt that he was able to make it look good like Shawn Michaels could. I never got that vibe that I could believe CM Punk could actually take the big guys down even though he did. I was more impressed with Fin Balor, but apparently he was sent back down to NXT or something, Idk... as I said, I don't follow it.
To each their own though. I know Goldberg wasn't a great wrestler and even now I will go back and watch his old stuff and constantly say 'that was pretty bad', but the story, the hype, the spear lol... it was fantastic for its time.
P.S. Best spear in wrestling, EASILY Goldberg. None of this Edge crap lol.
