Other than the legendary Eric Crumble (0-31) I'd say my favorite third tier is actually a man I was supposed to fight but it's never been arranged and that's Andrew Hartley (2-28). Also like Brian Strege (0-3) and Jason McClure (1-9) and a few others who I have become friends with over the years.
As for second tier fighters, I'd probably say the one who stands out to me because we used to be good friends was Brian Paul--- he was similar in record and pedigree to someone like Mitch Rose who had a good amateur pedigree but a pretty bad pro record, but once in a blue moon wins a match that's unexpected.
As for journeymen, I have alot of favorites like Stacy Goodson. Everett Bigfoot Martin was always a household favorite at home when I was a kid. And of course "Gypsy" John Fury.
