The truth is probably somewhere in he middle in his case. If Wiggins would have been called up for Sky's Tour squad, it would have been only for a supporting role. That's what Wiggins also acknowledged for quite a while. There is no question, that if Wiggins and Froome would get on well, that Wiggins would be in the team. There is no rational reason why you would leave a former Tour winner, who showed good form this season, at home. He would be a fantastic addition to any squad in the Tour, even more so as a first call domestique. But there are other things that play into it here. Froome and Wiggins in one team is potentially a deadly combination - that's what Sky is thinking at least - it could put Froome's title defense in danger, as any distractions can be difficult to deal with during a three weeks tour where intensity an pressure are on. I believe Wiggins when he said he would be ready to work for Froome during the Tour. But Sky doesn't believe so, or at least they believe with these two in the team, an escalation isn't far away. So that's why they leave Wiggins out of the squad. There is no margin for error in the Tour. Froome needs to be fully concentrated on the task ahead. Instead with Wiggins, there would be always questions from the media over the relationship of these two, how much Wiggins helped or not helped etc. which would lead to distraction. I understand Sky's decision from that point of view. They have a clear goal, and a clear number one to achieve this goal. They try to avoid any possible issue that could distract from achieving this goal. It's tough on Wiggins, who would be part of any other Tour squad. If he can win the Tour again isn't the question then. But that he would at least be able to challenge for a good GC position, that is ensured.
