Cheating, betting, and scandals have been a part of sports ever since the beginning, whether it's to gain a competitive advantage over an opponent, rake in some extra cash, or a temptation that was just too hard to resist.

The only thing worse than all of those things, though, is lying about it. Sooner or later the truth will come out, and when it does, get ready.

These 10 sports figures lied to millions of fans, and are worthy of being named the top 10 liars in sports history.

Petrino left the Atlanta Falcons overnight shortly after star quarterback Michael Vick was sentenced to prison.

The high school senior lied to a gym full of one thousand students and the local media when he said he would be going to the University of California to play division one football.

Earlier this year McGwire finally confessed to allegations that he had used steroids during his prolific career. The fact that he denied it for so long makes it difficult to feel bad for him.

Towards the end of the Miami Dolphins 2006 season Nick Saban was repeatedly questioned about the vacant coaching position at the University of Alabama. He denied rumors that he would leave Miami for Tuscaloosa at several press conferences and even went so far as to say "I'm not going to be the Alabama coach" in late December.

As soon as the Dolphins season was over Saban left for the Alabama job, leaving the Dolphins high and dry.
