Given the lack of talent on the defense the last 2 years, mediocrity is actually a significant accomplishment. Look at the defense last year and compare it to the defense from 2005. Or 2009. Who, aside from Heyward, would have started on those defenses? And before you say Timmons, he would start, but we would be next to Farrior (and over Foote), not in front of Farrior.
Regardless of scheme, you need talent.
