The Buffalo Bills have strengthened their defence by signing five-time Pro Bowl defensive end Joey Bosa on a one-year, $12.6 million contract. The Los Angeles Chargers let Bo Sá go because they are trying to keep some space in their budget. Now Jerry Hughes is taking over for Von Miller—who did not get much playing time because he was not performing very well right now. Despite injury struggles, Bosa brings experience and pass-rushing ability to a Bills defence that ranked 18th in sacks last season.
