‘If fans weren’t already obsessed with an NFL Draft class rich with wide receivers, the Diggs trade did it for them. Now, that’s not to say the Bills are a lock to pick a wide receiver with the No. 28 pick, or elsewhere in the draft. Buffalo lost enough valued veterans due to salary cap constrictions that you can’t count out a defensive head coach, Sean McDermott, pushing for help on the defensive line or secondary. Or maybe they add to the offensive line after losing center Mitch Morse, although that seems a little less likely after signing multiple veterans as depth additions.’
