I was thinking about this today and it seems like a convenient thing for Saxo Bank to have Contador free to ride (cleared by the Spanish fed) until after the Giro (appeal to CAS which will surely net a ban), where he could very well win.
Then, if his CAS outcome is a 1-year ban let's say, he would have the already served six months (August-February, when he wouldn't have raced anyway), get to count his results from now to the Giro (as Valverde did with the Vuelta and all of 2009; CAS said they had 'no reason to believe he doped in that time), then get suspended for July-December or something and be back next season. If he will get a ban, it's kind of like 'well, you lose your tour 2010, there's nothing you can do about it, and any suspension (1 year or 2) is going to mean you miss the tour 2011, but we can give you some results in between'.
Good for Saxo - if they don't have their marquee signing for the world's biggest race, they have him for the second biggest. Good for the UCi - somewhat assuages a sponsor that only stayed on board because of Contador. Good for Contador. Good for the Tour - the official disqualification of Contador will be in doubt for some time, and I'm sure the casual fan will not be sure whether to believe Contador doped... plus then when he comes back, it can be a Contador vs. Andy showdown.
By 'good', I of course mean 'better than a straight up ban'.
btw, what happened with Valverde there and CAS? I'm not sure why they let him keep his 2009 results but backdated his 2010 suspension. It almost seems as if they wrote their decision out before January 1st but it got hung up procedurally until May.
