I say: Lee Labrada. The guy is well educated, intelligent and elloquent. You rarely see a pro that is able to construct a decent sentence with a meaning, and Lee definitely was one of those articulate pros
I can't believe Ronnie Coleman even made your list. Don't get me wrong, I like him and think he has an amiable personality but Ronnie's dumb as a bag of rocks.
Did you see him on Leno?
Have you heard his post Olympia speeches? (How many times can he say "y'all" in 3 minutes?)
Besides, having a college education doesn't mean jack. Trust me, I went to college and even graduated with some guys that were pretty fuckin' dumb. They just stayed persistent and eventually passed all their classes. It's very sad but a college education is starting to mean less and less.
Flex Wheeler always seemed very articulate any time I ever heard him speak.
