Of course I wasn't saying that athletes A, B and C would never cheat if they were the best in the game. In fact, one of my other points stated why these some of these same players might cheat -- mainly their bodies and skills start to decline. I was pointing out the best have far less incentive to cheat, especially when you consider the drawbacks. For every Barry Bonds and ARod, how many others are there at the top of the game that were never suspected of cheating? How man Griffeys, Pujols, Trouts, Frank Thomas's, Jim Thomes, etc. were there? I can only assume that the great players who presumably never did cheat didn't do so because of the point I originally made. I'm already better than everyone else, so why take the chance damaging my body and my legacy? The lesser players have more incentive to cheat because they have a better chance of losing their job -- or losing the big payday -- without that extra boost in performance. You are right that I can't prove this statement, but I'm making an argument, not a proof.
