Even though he's not starting yet, Bengals defensive end Carlos Dunlap's playing time wasn't impacted due to Robert Geathers' return against the Buffalo Bills. In fact Dunlap posted the third-most snaps on the defensive line and generated five quarterback pressures (more than half of the team's total quarterback pressures).
Cincinnati played a significant number of nickel defense last Sunday, with Manny Lawson only posting four snaps on defense and Brandon Johnson not stepping onto the field against the Bills offense (though he did play special teams). Gibril Wilson was the benefactor receiving his most significant snaps of the season against the Bills, often playing safety while Crocker moved into a nickel role.
