Knocks against Vincent shouldn't be taken personally. He is a CB that failed to make the transition to S. It's not for everyone, and he didn't ask for it or want it. But they asked him to do it, he gave it a shot, and it didn't work out. Not his fault.
Now, I don't see why we would drop him. Don't need the money, and we have 3 rookie DB's that need some veteran help. Even if all these guys learn the D and Jauron decides to start them when the season starts, Vincent would AT WORST be a great Dime back, and excellent injury insurance.
