The Bills' O-line surrendered 261 penalty yards, second to the Dallas Cowboys.
Clearly, the Bills must improve in that area. They didn't seem to do that Monday by signing free-agent right tackle Cornell Green.
Green contributed plenty to the Raiders' high number of O-line penalties. He played in 12 games because of a calf injury, but he was tied for second among all NFL players in number of times flagged. Green was cited for 13 infractions, one behind Cowboys tackle Flozell Adams.
Bills fans have extra cause to be uneasy if the Bills keep Demetrius Bell at left tackle.
Bell led the league in penalties until his season was cut short by a knee injury. In just eight games, Bell tied for 11th in penalties with 10 of them.
Green and Bell combined to commit an astronomical average of 1.15 penalties a game last year.
As you can see by the attached chart, it's probably a good thing the Bills declined to tender a qualifying offer to restricted free-agent guard Richie Incognito. He led all offensive linemen with 115 penalty yards assessed. Nobody else hit triple digits.
