‘The Bills bid adieu to seven veteran starters. The roster is retooled. How quickly can Sean McDermott and his coaching staff get all the new pieces to fit seamlessly together and start producing at a high level? The Bills have enough speed on offense to suggest they can compensate for the loss of Stefon Diggs by spreading the ball around even more than they did last season. A lot is riding on new wideouts Keon Coleman and Curtis Samuel. The defense is solid. But the Bills will need step-up performances from Von Miller, Greg Rousseau and the new safety tandem if they want to win the AFC East again.’
