Quinton “Rampage” Jackson is one of the most decorated light-heavyweight fighters of all time.

He has won the UFC light-heavyweight championship. He unified the PRIDE middleweight title and the UFC light-heavyweight title when he defeated Dan Henderson in 2007. He has had one of the best fights of the past decade when he fought Forrest Griffin at UFC 86. So where does the problem lie with the man known as Rampage?

The problem stems from Rampage himself, more specifically how much desire and drive he actually has left in him. He “quit” in 2009 because he was upset that UFC and Dana White got mad at him for pulling out of his fight against Rashad Evans to film “The A-Team.” Then, he decided that he wanted to come back to honor his contract to UFC. The fight that he wanted, and got, was against Rashad Evans at UFC 114.

At the event, Evans was able to take the fight to Rampage. It was a good fight, but the problem with it, as far as Rampage was concerned, was that he looked slow. He was in good physical shape but something seemed to be missing from him in the fight. Not to take away from Evans and his performance because he had a strong fight plan and deserved to win.

After the fight, Jackson talked about the film and how he regretted doing that because he wasn’t prepared for everything that went into it like promotion and personal appearances for it. He said that it got in the way of his training for the fight, and that really affected his performance.

So the question remains: Does Quinton Jackson still have the strong desire necessary to be a force in UFC?

He did sign a new contract with UFC early in the year, and he seems intent on making himself completely committed to being the fighter that he was circa 2007, when he was one of the very best in the world. The proof will be in the pudding, and we will see how serious he is this Saturday at UFC 123 when he takes on Lyoto Machida.
