Yeah a lot has been said so far regarding this issue with the dog fights, and yeah he is innocent until proven guilty, but honestly Vick is most probably done in his NFL career.
From what I've read and know of the situation Vick was most likely aware of the fights going on at the home he owned but his cousin lived in. Also the fact that it did go to Virginia federal court tells me that the prosecutors have a pretty good case if not a rock solid one. Add to the fact that Vick and his co-defendants have opted for a jury trial tells me that his defense is going for a mistrial of some sort. With Vick being from Virginia and having played at Virginia Tech I can't see that even using the widest juror pool available from that state how he can get a jury of his peers that doesn't know of him and have an opinion either way. This tells me that his defense is not trying to prove his innocence but rather go for the mistrial instead which is like getting disqualified on purpose.
After all is said and done if found guilty or not Vick is going to have a tough time finding another NFL team to touch him. Not only for this, but his "I didn't know you couldn't take weed through an airport in a water bottle." incident and also in his 7 years in the league he's never thrown for more than 3000yds or more than 20 TD's, and as his experience grows so does his INT's. He is a phenomenal athlete and when he's good it's great to watch him, but even with all this talent he needs to make better decisions off the field as well as on it.
