I would hope that everyone on this site knows enough about this sport to know that all of the upcoming matches for each champ pose serious threats. Penn has already beaten Hughes, and even though Hughes is a different fighter, so is "The Prodigy", so who knows. Monson certainly has the skills to submit Tim, but the opportunity to do so is the question. Tito can beat Chuck on a good night, he has the skills, no matter what anybody says. And finally, anyone who doubts Anderson Silva's ability should watch some tape and see what he can do. I'm not saying he is the hands down pick, but he certainly has a definite chance.
