There really are no weaknesses in relation to other fighters. That said, Matt Serra once proved he's not unbeatable. In other words, if you tag him, he can be taken out.
What Carlos Condit brings to the table: Condit is a complete MMA fighter. We're talking about a guy that brings an even amount of submission (13) and (T)KO victories (13) into this encounter. He's technically sound on his feet, has solid wrestling skills, and is a well above average Brazilian Jiu Jitsu practitioner. He's capable of causing guys to tap from both the top and bottom position. What's more, he's showed a lot of power recently, having (T)KO'd Rory MacDonald, Dan Hardy, and Dong Hyun Kim consecutively. Not to mention, the guy won a controversial decision while mostly on his feet against Nick Diaz. Simply put, anyone who is able to have a level of success on his feet against a guy like him has cardio and possesses toughness.
The weaknesses? Well, he's a solid wrestler; but Condit can be taken down. And that's about it.
Georges St. Pierre vs. Carlos Condit Prediction: First thing's first- I'm going to assume, based on his athleticism and work ethic, that St. Pierre will experience minimal problems coming back from his injury. Could I be wrong? Yep. But all of that plus the hometown crowd should spur him on to his former greatness. So......On their feet, this one is close. I like St. Pierre's athleticism a little bit more. But in a striking battle this one could go either way, as Condit is an excellent striker. However, guess is that if St. Pierre wants to put his UFC 154 opponent on the canvas, he can. And that's significant, as it offers St. Pierre a couple of options. In the end, I expect the Canadian champion to strike a little bit before taking this fight to the canvas. Once there, expect him to pound on Condit for several rounds. It won't be easy, as Condit is dangerous off of his back. Then again, the man they call "Rush" has dealt with BJ Penn off of his back, so he's very capable there.
Georges St. Pierre defeats Carlos Condit by decision.
