‘For now, the Bills appear set with Dawson Knox as their starting tight end. It would be fair to say this is put-up-or-shut-up season. The Bills want substantially better production from the tight end spot. Unless they make the much-speculated acquisition of Philadelphia standout Zach Ertz, or another player who would represent an immediate upgrade at the position, they’ll be counting on Knox to perform at a higher level than he has shown the past two years since arriving in Buffalo as a third-round draft pick.’
