Yes he has.
At one stage his O-Line was on pace for most sacks in a season. The O-Line has currently allowed 49 sacks, 1st in the league.
The Bills and Chiefs 2nd with 44. Steelers are "3rd" with 43.
And call me a homer, but I honestly believe Ronnie Brown, if he had've stayed healthy, would be in the Top 5 list for RB of the Year.
