I found that interesting... but was not heartened by it.
I continue to believe it's an ongoing problem... not a back breaker but certainly an Achilles heel when facing the stronger competition in the NFL.
I also continue to believe it's a 'scheme' issue more than a personnel issue. Although it's possible it could turn out to be both.
No solution from me here... do you sacrifice some efficiency in the passing defense to bolster the run defense? I'm not too keen on that, but depending on the opponents strengths it may be necessary. - JamesJM
