I agree that Bos is a phenom athlete but I don't think Euro road racing is in his near future. It takes years, and years to develop the endurance to make it 80 - 120 miles and then unleash the fury. I just don't think he'll have the time to do that before he gets too old for a ProTour team to continue to want him. If he came to the states and raced hour long crits, mixed in with week long stage race like Altoona and Georgia, that might be the best balance of developing into a roadie, and have the frequent success of victory on the road.
I'm excited thinking about his transition. Would love to see him doing longer track stuff like points racing, scratch, team pursuit, and madison.
