Here's a prediction on Michael Vick: He doesn't become eligible to play again in the NFL until 2009.
I'm going to put this on fast-forward. Unless there is some exculpatory evidence out there (proof that would help exonerate Vick) that his camp is being inexplicably silent about, he has to plead guilty -- and do it very soon. Like in the next few days -- if we are to believe the timing of an impending superseding indictment that could add more charges to the ones he already faces in the alleged dogfighting-gambling scheme based out of a Virginia property he owned. One of three co-defendants has already pleaded guilty and two more are scheduled to do the same tomorrow.
Assuming Vick follows suit, figure on a sentence of about a year -- if he's fortunate. Then, NFL commissioner Roger Goodell has to decide whether his NFL discipline time basically should run concurrently with his prison time. Considering what Goodell has done in the case of Adam "Pacman" Jones, Chris Henry and others, allowing Vick to play again as soon as he's released would mean that his NFL penalty would be the same or not much harsher than the others. Think Goodell is going to do that? Me neither.
Bottom line: 2009 at best.
