The Buffalo Bills are encountering significant challenges as they open their offseason training activities (OTAs). Running back James Cook is notably absent, reportedly amidst ongoing contract negotiations, making him the only player missing from voluntary practices. Coach Sean McDermott expressed confidence that Cook will return when ready. Meanwhile, defensive end Joey Bosa is sidelined with a calf injury sustained during team workouts, raising concerns about his availability for the foreseeable future. The Bills are hoping for a quick recovery as they aim to strengthen their roster with new talent, including a standout performance from a new wide receiver. Additionally, former NBA star Vince Carter made an unexpected appearance at the OTAs, providing a moment of excitement amidst the injuries.
