Last year was an exciting year (through about week 8 or so). The Bills were close last year, but a rash of injuried derailed their season. The same thing could happen this year, unless we stay a little more healthy.
On paper, the Bills look better. I am much more confident with Wannstedt running a 4-3 with Mario, Kyle, Dareus and Mark Anderson on the line than I was last year with our horrible DC, trying to run a 3-4 with two defensive tackles and no "real" defensive ends. But the entire season will hinge on the ability for our key players (Jackson, Jones, Wood, K. Williams, McGee, Merriman, Lindell), staying healthy. All of whom listed, ended up on IR.
Rest assured, the Bills will win more than 6 or 7 games this year, unless of course our IR report looks like Fitz, Wood, Mario.
