What we have to remember, Bill, is that Armstrong does not own this team as he did the previous teams Bruyneel directed for him. The commentators keep calling it "Lance's Team," but it's not his team.
This means that Bruyneel, who sets the race strategy and reports to the team owner who pays him, gets to say who rides for whom. The current posturing is for the influencing of the owner-- "Who do you REALLY believe can win this puppy for you?"-- and the riders-- "Who will youse guys carry to the top of Ventoux?"-- more than for anyone else.
