He's not listed, but Matt Cassel will be also be a free agent in 2010.
That is a lot of talent. You would expect guys like Manning and Roethlisberger would be resigned by their teams, but you never know what kind of money they'll be asking for.
I don't think there's a guaranteed connection, but it does seem as though players often have career years when they just happen to be playing for a contract. All these guys will be playing for a contract this year, so you might want to move them up your draft list a spot or two.
