"Doubled" sounds unlikely, max. The other guys who also got sentenced, all of whom had pleaded guilty before Vick and none of whom had financed the whole thing like he did, got at least 18 months each (I think) even though (as far as I know) none of them failed a drug test like Vick did. His sentence was pretty clearly going to be stiffer than theirs regardless of the drug test, but if that had led it to being doubled, it would mean he was going to get only 11 or 12 months, which doesn't seem the least bit likely.
