Mas and Bergan will win the TDF one day, maybe more as long as they have good support. I think Lopez might be the first to win a GT out of the three, but doubt he wins the TDF at this point. Depends on the parcours for Lopez. If Mas truly has Contador-esque talent, he will win a lot after the Froome Era is definitively over. Right now Bernal looks like a sure winner. My only concern is whether his trajectory follows the Nairo model of career peak.
