The talk around these parts about the defense giving up drives at critical times got me to thinking about D in general. Over the history of football, defenses have evolved to meet changes in the offense. The 6-2 gave way to the 5-3 and 5-2 Okie. Those defenses gave way to the 4-3 and 4-3 slide. Then came the cover-2 (and later Tampa 2) and the zone blitz. As we all know, the rules are quickly changing to favor high powered passing attacks. Defenses will have to adapt and find new ways (and they will, they always do). So here is the question - how are defenses going to adapt? Are they going to focus on rushing the passer and blitz schemes? Will they look for fast defensive backs with big vertical and can play the ball rather than rely on bump/run? Will teams continue to base more out of nickle packages or will there be some radical change to coverage Safety or coverage type LB? What say you - how should defenses adapt to the pass happy rules and the new "contact" rules?
oh - and to keep it Steeler related - how would you apply your changes to the Steelers? Use specific examples (like move Timmons to MLB and go to 4-3, etc).
