And I'm pretty sure this is a question that both Brailsford and EBH have asked of each other over the past year. Personally, I don't think it is true to suggest that EBH hasn't improved - he has, but through diversification in that now he is strong in medium mountains, time trials and classics. Don't forget also, he only just fell short in Flanders this year: had Cancellara attacked later on the climb, EBH may have stayed with him. You can't fault him for not keeping up with Cancellara. Few riders do. I don't think GTs were ever on the table, and he would admit this himself. Perhaps one week stage races.
So it was a good question worthy of being asked. The situation wasn't great, and I really feel for EBH, who was there, don't forget, when Kimmage asked it. That was a little out of order. One on one with Brailsford, fine.
Now Kimmage, good writer that he is, usually has a subtext when it comes to cycling. In this instance, what was it? Is he suggesting Wiggins/Froome leapt over EBH because they are on a programme and EBH isn't? If Sky have a programme, then EBH would definitely be on it: if he has the talent, then he would only need a little (less risky) pick-me-up than the boatloads of pharmaceuticals many believe Froome needs, for example. For a details man like Brailsford that is a no brainer, but conveniently ignored.
I think, perhaps, Kimmage thinks EBH IS NOT on a programme, and he hopes that by flattering him somewhat, and causing some internal strife, that EBH may spill the beans to Kimmage. That could be his long game (though could take a while as Lovkvist for example has said nothing). But his opening gambit was clumsy.
