From one extreme to another, we now take a look at how well the New England Patriots' run blockers performed at the point of attack.

For his book, Scientific Football 2009, KC Joyner has broken down the game film to determine how well each offensive lineman fared last year.

Joyner considers an 80 percent point-of-attack win percentage to be borderline acceptable. The first team we presented, the Buffalo Bills, had two linemen who met that threshold last season. The Patriots, meanwhile, went 7 for 7.

Across the board and including two backups, the Patriots graded out at 84 percent or better.

The accompanying chart breaks down a lineman's performance by net point-of-attack attempts (plays in which he was at the point of attack plus penalties committed and drawn), yards gained on these plays and his run-blocking success rate.

Among all AFC East offensive linemen, left guard Logan Mankins was involved in the most rushing yardage gained while blocking at the point of attack. The next-closest lineman from a division rival was New York Jets right guard Brandon Moore with 915 yards.

Joyner tracks the number of times a lineman gets stuffed, pushed into the backfield or strung out, or allows a defender to make contact with a ball carrier in the backfield.

What stands out most about those stats for the Patriots is that they were pushed into the backfield 11 times as a team, second-most in the division to the Buffalo Bills' 22 times.

Center Dan Koppen was pushed back six times, tied for second-most in the division. He allowed six defenders to make contact with a ball carrier in the backfield, also second-most.
