5. (opinion on Lance Armstrong)

 There's certainly no denying that Lance Armstrong is an incredible cyclist, and is also a very inspirational person after his battle with cancer.  His contributions to LiveStrong have raised huge amounts of money to a very worthy cause.  However,  I still think that his use of performance-enhancing drugs and especially his later denial of the mistakes he made outweigh the many pros in the grand scheme of things.  Let's face it, it's really not that uncommon to see the use of performance-enhancing drugs in sports these days.  It actually happens quite often.  The factor separating Lance from the pack is the fact that he used them in a way that lended itself to his not being caught, and then repeatedly earned accolades and accepted them under false pretences.  For many years, he told the press, publicly stated, and even wrote in his memoir that he never took any drugs.  In my mind, it's one thing to break the rules (a thing you should stay away from at that), but another thing entirely to lie about it.  As much as Lance has been a great person in other aspects of his life, it's just kind of hard to look up to someone who has been revealed as a cheater and a liar.
