‘Defensive coordinator Dennis Allen likes employ man-to-man coverage. The last team to employ that against the Bills was the New York Jets, and Allen and his receivers shredded them for 366 yards and two touchdowns on the way to a 45-17 victory. Of course, the Jets’ secondary (as with so many other parts of their team) is terrible, and the Saints are stronger in that area. Still, Stefon Diggs and the rest of Buffalo’s pass-catchers should excel in one-on-one situations. Allen could always utilize some two-deep zone coverage, which has given the Bills problems, but coaches usually stick to what they know best. Man-to-man coverage is what Allen knows best.’
