I agree with the general 'get a grip' tenor of your comment - if Horner likes Lance, well, at least someone does. It shouldn't be an issue. And calling top ten at the TdF 'has been'... that's just bizarre. I would call that 'is right now'.
Still, your comment plays up a problem with the RS team this year and many other cycling teams at various times. If you are the strongest, the best way to help the team is to win, or go as close to that as possible (if the team's real goal is a team result). Everyone on a team must fall in line, but fall in line behind the strongest or best placed rider. In a real team, you don't care who does best - you just try to get the best finish for the team. If RS was a real team, they would have told Horner to go. As it is, he was held back, hurting his own chances of success and the team's. As someone who has followed his career for a while and think he is a pretty decent rider, I think this is a real shame.
