Whatever Happened To Cheat To Win?

If you are gonna dope, shouldn't you be at the top of your form when it comes to the big races?  I understand that the PE drugs are everywhere, but at least Armstrong followed an insane training regimen in addition to being doped to the tits.  When everyone has the tip-top pharmaceutical add-ons, you still gotta want it more and train harder.  Shreks Schlecks don't understand that, I guess.
