It was in my lifetime IMO.
Sure the scheme sucks and hurts the offense, but that same scheme for the DL for 6 years was never quite as bad as it was this year.
This year I saw our DL players struggling mightily in getting a push, getting off blocks, and making tackles. More than any other year before or after Tuiaki was hired.
*If no, please state what year you think we had a less talented overall DL.
