Lance Armstrong... greatest doper there was or ever will be

Losing sponsorship and you'll lose teams, like HTC-Highroad, rosters will be smaller, it will be harder to get a contract, we'll get even less TV coverage.

Yes it won't kill it, but it will hurt it.

I'm not sure how people arrive at these kind of assumptions. Stricter/more effective doping control and a 'cleaner' attitude within the sport in recent years have actually seen an increase in major sponsorship and tv coverage.
