‘The Bills are bona fide contenders, with little to suggest they’ll take a step back. They have a majority of offensive starters back, plus coordinator Brian Daboll, putting Buffalo in position to match and even build upon last year’s production. The question is whether the defense can shore up its inconsistencies to contain some of the NFL’s more dynamic offenses. We’ll get a better picture in back-to-back weeks in mid-October, when Buffalo plays Kansas City and Tennessee, who accounted for three of the Bills’ four losses last season.’
