Well obviously McDermott and Frazier know what they're doing...I am just hypothesizing but it wouldn't shock me if we were to play Tennessee again and they went to a more traditional 4-3, if only because Henry and the Titans offense attack you in such specific ways. The Bills are rightly confident in their base nickel but I do wonder if letting the front 7 play the run more traditionally, against an offense that is built around the biggest mismatch RB in the game, would be better option than needing to rely on DBs crashing down the line to hit him below the waist.
