Bills' toothless run D to face toughest task yet

Posted by ESPN.com's Tim Graham

Is it possible that during the bye week the Buffalo Bills reinvented their defense and discovered ways not to get trampled Sunday?

They rank dead last in rushing defense, allowing 173.6 yards a game and 5.1 yards per carry. Johnson

Next, they get the Tennessee Titans at LP Field. Titans running back Chris Johnson leads the NFL with 959 yards and is maintaining an extraordinary average.

Johnson is gaining a league-best 6.7 yards per attempt.

If he can keep that pace for the rest of the season -- and he might very well improve on it against the Bills -- he will finish with the second-highest average in NFL history. Beattie Feathers averaged an obnoxious 8.4 yards a carry for the Chicago Bears in 1934.

Only four other running backs have led the league in rushing yards and averaged 6 yards a carry:

  • Jim Brown, 1963 Browns: 1,863 yards, 6.4 average.

  • Barry Sanders, 1997 Lions: 2,053, 6.1 average

  • Joe Perry, 1954 49ers: 1,049 yards, 6.1 yards.

  • O.J. Simpson, 1973 Bills: 2,003 yards, 6.0 average.
