When it comes to plea bargaining, Vick has a problem. Based on the indictment, he appears to have bankrolled the entire dogfighting operation, which began after he became a wealthy professional athlete.
Nevertheless, the two reasons why Vick may still be able to make a deal are: First, there would be a value to both sides if Vick is the first defendant to try and do a deal the government would be more likely to accept such a deal than if he were the last defendant to seek a deal. Second, the government knows that if it has to actually try Vick, it will be going up against a high-powered defense team, including prominent D.C. attorney Billy Martin, whereas, if they do a deal with Vick and take the other three defendants to trial, they will not be facing anywhere near as well-financed a legal defense.
