Georges St-Pierre regrets his losses, and even a few of his wins

In more than a decade of testing himself against some of the gnarliest killers the welterweight division has to offer, Georges St-Pierre fashioned one of the greatest careers in MMA history.

St-Pierre's list of high-profile triumphs is staggering, and his losses were all violently avenged. 

Despite this successful reign of terror, "Rush" still has a few regrets, and wouldn't mind punching a DeLorean to 88 mph in order to correct his past mistakes.

"If I had to do it again, of course, there is some stuff I would change," St-Pierre told reporters prior to weigh-ins for UFC 186. "You are never 100 percent happy with what you do. I am very critical of myself. There are some fights I didn't like. There were training camps (that were not perfect), there were times where I wished I would have prepared myself more adequately. But, that's how you gain experience. You can't change the past, you can only change the future."

Not only would St-Pierre like to erase the losses from his ledger, but he has a few wins he'd like to do-over.

"My loss to Hughes, my loss to Serra. My first fight with BJ Penn, I hated," St-Pierre said. "My fight with Jake Shields, I hated. My fight with Diaz, I despised it, completely. My last fight with Hendricks - I was not happy with it, at all."
