ORCHARD PARK, N.Y. (AP) — Out of the doghouse and back in the Buffalo Bills' starting lineup, cornerback Leodis McKelvin is determined to prove himself no matter how daunting a challenge it will be to prepare for Tom Brady and the New England Patriots.

McKelvin can't pick and choose his opponents nor control the circumstances behind why he's risen up the depth chart. He's jumped ahead of two injured players: starter Aaron Williams and veteran backup Terrence McGee.

So if the game at New England (5-3) on Sunday marks the 2008 first-round draft pick's latest — and potentially last — chance at showing what he can do as a starter in the final year of his contract, then McKelvin's going to go out smiling.

Of course, it won't be easy for McKelvin or the Bills (3-5), who are 2-19 all-time against Brady.
