when everything goes well for him he seems fine but he has a different side about him that you don't want to find out.... also very insecure.
^this
his insecurity leads him to unfairly impact others when he's under pressure, ie. he can't handle pressure like an adult, not even to the level of other sprinters (exception perhaps being Graham Brown).
For example, publicly *****ing at Greipel, the two fingered salute, the erractic sprinting taking down Haussler and the other riders (ending their TdF before it started) and the failure to actually apologise for that....
...not to mention the stupidity of ignoring the dental surgeon's advise not to train after his tooth op, resulting in the infection which seriously impacted his own team's results so far this season (since almost all of the team is built around him).
So he can win all the races in the world, and he'll be happy and thank his team mates like he should....but if things don't go his way, he starts hurting other people.
Also, as a rider he's actually very one-dimensional. He can win sprints from an (excellent) train. If Cav's ego and ability could have handled it, Greipel could have been in MSR and he would have had a chance....but Cav can't seem to win unless practically the whole team delivers him to the line.
eg 1. Greipel was asking HTC for selection for MSR and talked about this to the media, and i don't think he specifically referred to Cav at that time, but Cav then takes it personally, and slates him hardcore in the press. When Cav then doesn't perform at the race, he doesn't apologise, he makes excuses, then on the next race he wins, gives a two fingered salute. Talking sh*t in the bus or on camp is one thing - publicly putting your own team mate down just because he stated his own case for selection is another.
eg.2 Still not winning and therefore feeling very insecure, Cav
