I do think Evan's highly strung personality, extreme sensitivity and paper-thin mental toughness contributed to his poor time trial. These character traits burn up a lot of energy, and I think this may have proved the difference between him winning and finishing 2nd.
However, much of his behaviour is simply inexcusable. He is not a youngster, but a veteran approaching the end of his career and should know better. I also agree with others about his motorhome, bodyguard and entourage - it's a shame his results don't match his ego. In my opinion he is a spoilt 3 year old in a squeaky voiced man's body.
