Sometimes the way he races, pretty passively, annoys me
We all have our reasons for liking or disliking riders, but you do realize although riders are paid to entertain that is not what motivates them?
Riders are paid and motivated to win. You win based upon ability, hard work, team support and courage. I think its too early to say Mas lacks courage. He is riding to his physiological limits. This Vuelta he stepped up another level. Clearly better than Haig and the rest , but nobody was close to Roglic. Others might disagree but I think the field at this Vuelta was deep and the level high. Mas finished 2nd, good job!
Had Mas attacked he might also have blown up any chance of a podium. If on big MTFs if he is riding above his threshold then he simply won't be able to attack even if he wanted to. That's how the physiology works. Entertaining riders in the past (like Contador) were not riding at their threshold when they attacked.
