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.
Sosa, like several other athletes on this list, lied to Congress in 2005, stating that he never used performancing enhancing drugs.

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

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.

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.
Palmeiro lied directly to Congress in 2005 about using performance enhancing drugs and it wasn't long after that Palmeiro was suspended for using steroids, just after reaching 3000 hits
