While I'm certainly not a Lance "fan" and he and I would not see eye-to-eye on a great many topics, I do have tremendous respect for his athleticism, riding ability, competitiveness, mental-acuity and ability and willingness to use his "celebrity" for something good. He's not required to give anything back... really none of us are... but he absolutely has given back! I can think of no other rider in the modern era who has singlehandedly done more for the sport of cycling.
