The 2013 Buffalo Bills season was highlighted by the impressive debut of rookie linebacker Kiko Alonso, who earned multiple Rookie of the Month honors, and a powerful rushing attack that ranked second in the NFL. Under first-year head coach Doug Marrone, the team showed great promise and resilience, featuring standout performances from Pro Bowlers Mario Williams and Kyle Williams, who led a formidable defensive front that recorded a then-franchise record 57 sacks.
