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
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.
