Assuming that DZ, JV, Levi, Jemison and others all told the truth, a truth similar to TH, GH and others, then he has quite the uphill battle. This isn't compared to the Bonds case where one guy went to jail for him, and the feds still almost got him.
I think LA will stay firm and wait for an indictment, and see what's in it, and how to proceed. Then he has two general options:
1) If it is filled with numerous counts, and revealed that numerous people testified to his doping, and all seem to be consistent, I would think Lance's attorneys would be looking to broker a plea deal, and hopefully help feed the UCI to international courts, making them a bigger fish. This would allow Lance to stay out of prison, give a mea culpa along the lines of Tyler "we all doped, I'm sorry. But the sport is rotten and facilitated it. Had no one doped and the UCI really tried to stop it, instead of encouraging it, I would have never doped." This will of course send up a howl of protest, and he will lose a great deal of respect, and money, but still have a tiny bit of face with the most hardcore fans, and attempt in some way to keep his cancer fighting going, after much time passes.
2) But if the indictment is filled with enough cracks, let's say several riders and staffers, are quoted as saying they never saw any doping, and that they saw or heard FL, TH, even GH say negative things about Lance, and there are few bank/tax/money trails linking to doping, they could consider trying to drag this out as long as possible, and either hope for an acquittal, or strike a lesser deal at the last possible moment before the jury in the trial goes out. This would still be pretty damaging to his reputation. But he could try to spin his way out of it in the public opinion over time.
I'd say the chances of him either walking completely free, or getting back to where he was in the public eye a few years ago where people think those who complain about him are bitter and jealous, and he's the one telling the truth, are over.
