The Buffalo Bills were bad in the areas they were supposed to be good and good in the areas they were supposed to be bad in last season. In his first season as head coach, Rex Ryan coached the Bills to an over-achieving offense with surprising success from the quarterback position and a lethargic defense that was completely inept at causing havoc behind the line of scrimmage.
Mario Williams, one of the best pass rushers in the league and recipient of a nice, fat contract extension in recent years, went from having double digit sacks to being a complete afterthought.
