What's not relevant these days is whether or not defensive players are considered starters or not. That's especially true on the defensive line, where Frostee Rucker didn't start, but played only six less snaps than Michael Johnson. It's typically always relevant to the situations and group substitutions when these guys play. People demand that Carlos Dunlap start and play every down, but considering he typically only plays passing rushing situations, it's a big reason he's leading the team with 14 quarterback pressures, nearly triple the next Bengals defender. And with only 21 snaps against the Jacksonville Jaguars on Sunday, Dunlap still posted a team-high three quarterback pressures.
Taylor Mays was active for the first time this year, but didn't play any defensive snaps and safety Gibril Wilson posted a season-low three snaps -- mostly due to the fact Jacksonville played a primary rushing offense which kept Wilson off the field with limited nickel situations.
Linebacker Brandon Johnson got some work when middle linebacker Rey Maualuga left the game with a rib injury (later returned). Johnson has 17 defensive snaps all season.
