‘Bills general manager Buddy Nix and head coach Chan Gailey believe that Tarvaris Jackson, who did not participate either in the Bills’ spring practices or preseason camp, is a better option as the team’s No. 2 QB than either Young, who did participate in both, or Thigpen, who has been on the team for 13 months. That’s less an endorsement of Jackson than it is an indictment of both Young and Thigpen.’
