I like his look and find him interesting. While "Mr. Wonderful" was never a major star or great technical wrestler or anything, he was a good heel, good on the mic and really knew how to get heat. Had a good mind for the business. And it seems like he's been even more successful outside of pro wrestling.
I was reading about Riddle and how he started & ran a fan club for Rip Hawk & Swede Hanson when he was 14, and he would make business cards and fancy logos on jackets promoting them, and due to his dedication, the fan club was eventually brought to the attention of Rip Hawk at a show in Greensboro, NC. Apparently Rip came up to Riddle, started talking to him and asked if he was serious about the fan club and the wrestling business and told him that if he was, he would help him. I thought that was pretty cool, as i don't know that there were too many wrestlers, particularly heels, who would've done something like that back then.
Actually it wasn't even pro wrestling through which i originally discovered Rock Riddle, it was actually through a movie i saw him in years ago, Blue Collar from 1978, which starred Richard Pryor, Harvey Keitel, Yaphet Kotto & Ed Begley Jr. Riddle only had a small part in it as a thug, but i thought he looked cool and i looked him up on IMDb and came across other acting roles of his, but also of course found out that he was a pro wrestler, and so i did search and found out more about him.
