There was nothing wrong with GB's tactics. By far their best chance of the win was to get Cav to a bunch sprint. Obviously getting him to a sprint was gonna be tough but with a bit more help from other teams they cudda done it. Its silly to say 'they shudda had a plan B' because you cant have a plan B - the riders are knackered trying to execute plan A. Its pathetic that because Sky/Team GB dont win every race people say they are tactically poor!!
