The Buffalo Bills reached a three-year, $2.2 million agreement with guard Ross Tucker, 24, that could grow to $3.2 million depending upon his playing time. Tucker is a great success story for the Bills, a former undrafted player claimed off waivers from the Dallas Cowboys who ended up as the starting RG the final 5 games of last season. The 6-4, 316-pounder is projected to be a starter next season. Included in the deal is a $225,000 signing bonus. He was scheduled to be a RFA.
