The Facts: Further signaling their intentions of throwing open the starting quarterback job for off-season competition, the Bills have added a third candidate to the mix, reaching agreement with Nall, an unrestricted free agent, on a three-year contract.

Diehards Line:Nall is expected to compete with holdovers Kelly Holcomb and J.P. Losman for the starting spot. Losman was the team's first-round choice in the 2004 draft, but as ESPN.com insider Len Pasquarelli noted, there is a new staff and a revamped football structure in Buffalo, and general manager Marv Levy and coach Dick Jauron don't have the same loyalties to him as their predecessors did.
