I lost a lot of respect for RK. He flat out lied, not just once, but several times using different lies. That few minutes of racing followed by his lies is the worst thing he could have done for his 'job interview'. I can't see teams lining up to sign a guy who can't be trusted in a race, and is dishonest.
And what should he, in your opinion, say even if it was his fault? "Sorry guys, I lost my head and I rode for myself?" Even the team would not allow him to say that, because obviously no one wants to admit fault and show weakness. I´m not defending him, if it is true, he should have stayed with Alberto, but what can they do now other than do not admit it. It is very sad, but it happens. They are not machines.
A lot of people forget about the past, which was already mentioned above - Tour 2013 and all of the other stage races when he raced exclusively for Alberto. I think that he does not deserve this trash talk.
