In reply to Alun:
The Brailsford way is to have a very simple plan, let everyone know what it is and stick to it. Dominate and control the race, break everyone else's spirit. And very successful it has been too, both on the track and the road. But Contador's tactic is to play his cards much closer to his chest - stick to Froomes wheel but not to give away too much information on his current form. And of course say he isn't interested in winning this race, that he's not ready yet.
The Plan A and only Plan A tactic failed badly in the Olympic road race, partly because the team wasn't strong enough, and partly because everyone else knew the plan, let Team GB do all the work and didn't join in and then attacked a tired team at the end. Froome may be strong enough to do his part, but the lack of strength in the team will make him vulnerable over 3 weeks.
