Money, fame, and sports. What would happen if they raced without tv coverage for a trophy with no money? Remember High School sports Rob? The pressure to win and get the scholarship to make your way to the pros via college. Anything that creates such huge differences in status is ripe for cheating. Now even Golf is suspect....Better to play than compete.
I'll stop competing, then. ;)
At least with Rasmussen out, Discovery is almost sure to win the Tour with Contador, with Levi Leipheimer taking at least 3rd--maybe 2nd if he does well in the TT Saturday.
It's a bit of a soap opera. Still love to watch. Grieving the complications -- all of them -- crashes, cheating, etc.
