ORCHARD PARK, N.Y. — Buffalo Bills rookie quarterback Nathan Peterman continued making his offseason-long case to secure the backup job in a preseason-ending 27-17 win over the Detroit Lions on Thursday night. The fifth-round draft pick out of Pittsburgh finished 9 of 11 for 81 yards. Peterman played two series, which ended with Jonathan Williams scoring on a 21-yard run and Stephen Hauschka hitting a 30-yard field goal.
