Damn, this would be a real competitive fight, and one I'd like to see. Joe Stevenson has much more aggressive takedowns, obviously he'd be able to control Florian on the ground. I have to disagree that Stevenson has the better striking. Florian showed a more complete striking game than Stevenson ever has, and he also incorporates those NASTY leg kicks into his gameplan. The last time I saw Stevenson use leg kicks, he was falling on his ass.
Stevenson would probably win this fight, but would Florian ever give him a fight. The guy is tough and I like watching him scrap.
