Most of what I want to say has been said, but some things to think about: Renshaw wasn't in the finals selection in MSR because a team leader was, and so his team didn't chase. They won the race, seems it was the right move.
He spends most of the season riding got others, and riding in tours. He seems to be the best at this in the world.
His last two races, prior to ToB he didn't perform in, but in Plouay out lasted EBH and Cooke. Just like those guys Renshaw was racing Plouay for the miles, not a result. At vattenfalls he had 4 bike changes and a wheel change in the first 80km. So I'm not sure it's fair to judge him on that.
Haussler and Cooke haven't done much all year. Sutton wins a stage of the Vuelta and everyone talks up the relevance of grand tour stages. Sutton is dropped before the end in a stage in the Vuelta, that Bennati wins, and we hear **tumbleweed**. Renshaw is a star and key man for Cavendish during the tour and we're told that Grand Tour's are irrelevant (but what about CJs win?).
Renshaw wins a stage of the Tour of Britain, and finishes second to the man he is leading out, twice, and we're told ToB is too easy and irrelevant. Even though Swift and Thomas, two men Sky close over Sutton for the TdF were there competing. Forster was there, Hushovd was there, Bos was there. Renshaw could only beat whoever rocked up, and he did that, whilst working for Cav, and setting him up...what more was he meant to do?
Whispers about political decisions don't appear from nowhere. There are other riders who have missed selection previously (and this year), who have received much less publicity.
I think it's quite clear this wasn't a 100% sporting decision. It was a politically motivated/personal decision, that they have JUST enough doubt created to allow them to justify it as a sporting decision.
Quite disgusting really.
The point isn't about if Renshaw turns around and wins loads of races for Rabo next year. The point is that he should be there as a helper. The role he plays as well as anyone all year. If this course isn't the one for Renshaw, what is? If this was a one off pro team race, you can bet HTC would be taking him. In fact, I'm sure basically any team he rode for would be taking him.
