On the bright side, this should make the Giro a far more exciting race.
afx, I appreciate your "glass half-full" mindset. Wish I could share it. In any sport, you'd like to see the torch passed along in a legitimate manner. Even when Michael Jordan retired from the Bulls (the second time), you still had Stockton, Malone, Robinson, Shaq, etc. around in the NBA. In this case, you had Armstrong retiring, with the absence of Basso and Ullrich compounding that loss. So while all of the grand tours might be exciting, there would be a "tallest-midget" element to them.
