You mean, like when Lance Armstrong got caught?
It was less than 20 years ago and yet you still argue like it didn't happen. Undetected doping was indeed possible (he did it for years) and no it didn't destroy pro cycling…
i don't know how hard pro cycling was affected after his bust, i just remember reading that it took a few years to recover (i.e. a few teams got dissolved, some sponsors jumped ship).
even today, if you talk about cycling to an outside person the FIRST thing they ask you about is doping.
so in my opinion, professional cycling is on its doping redemption part - forced, whether they want it or not - because if they (and by "they" i mean Pog) get popped big time again, it's going to be viewed as irredeemable. they'd have had their chance after LA and blew it.
