Note: Since snap counts from the Bills' loss to the Houston Texans were lost in the quarterback shuffle last Monday, we will include those in parentheses for each player.
Mario Williams -- 47 of 62 (Last week: 52 of 68)
Jerry Hughes -- 45 of 62 (Last week: 35 of 68)
Jarius Wynn -- 26 of 62 (Last week: 30 of 68)
Manny Lawson -- 11 of 62 (Last week: 19 of 68)
Quick-hit thoughts: We're seeing a little bit of a separation between Wynn and Lawson, with Wynn seeing the field more often than Lawson. The Bills used a five-man look on their defensive line for at least one play, which factors into this mix.
Marcell Dareus -- 57 of 62 (Last week: 55 of 68)
Corbin Bryant -- 36 of 62 (Last week: 31 of 68)
Stefan Charles -- 20 of 62 (Last week: 23 of 68)
Kyle Williams -- 0 of 62 (injured/inactive; Last week: 27 of 68)
Quick-hit thoughts: Dareus stepped up in a big way, playing 92 percent of snaps with Williams sidelined. The Bills used close to a 2:1 mix between Bryant and Charles.
Preston Brown -- 62 of 62 (Last week: 51 of 68)
Brandon Spikes -- 51 of 62 (Last week: 42 of 68)
Keith Rivers -- 17 of 62 (Last week: 58 of 68)
Ty Powell -- 0 of 62 (special teams only; Last week: 4 of 68)
Larry Dean -- 0 of 62 (special teams only; Last week: special teams only)
Randell Johnson -- 0 of 62 (special teams only; Last week: injured/inactive)
Nigel Bradham -- 0 of 62 (injured/inactive; Last week: 27 of 68)
Quick-hit thoughts: The surprising decision here was for the Bills to opt for Spikes instead of Rivers in their sub package. Spikes isn't known for his speed or coverage ability, so that opened up a potential liability in the pass defense. It ended up not being a major issue, so job well done for Spikes and Brown in the nickel.
Stephon Gilmore -- 62 of 62 (Last week: 68 of 68)
Leodis McKelvin -- 54 of 62 (Last week: 56 of 68)
Nickell Robey -- 41 of 62 (Last week: 27 of 68)
Corey Graham -- 29 of 62 (Last week: 8 of 68)
Ron Brooks -- 0 of 62 (injured/special teams only; Last week: special teams only)
Ross Cockrell -- 0 of 62 (inactive; Last week: inactive)
Quick-hit thoughts: Doug Marrone said he wants to "get the snaps equal" between Gilmore, McKelvin, and Graham but that has hardly been the case the last two weeks. He rode the hot hand, McKelvin, against the Texans and didn't turn to Graham much Sunday in Detroit. Some of Graham's snaps came at safety when Da'Norris Searcy and Aaron Williams were both banged up.
Duke Williams -- 57 of 62 (Last week: 39 of 68)
Aaron Williams -- 50 of 62 (Last week: 68 of 68)
Da'Norris Searcy -- 17 of 62 (Last week: 28 of 68)
Quick-hit thoughts: This position continues to get hit by the injury bug. Aaron Williams appeared to have a wrist or hand injury during Sunday's game, although nothing was announced by the team. His time was limited after that injury. Searcy also headed to the locker room with an injury, the second time in three weeks he's been banged up. That led to an uptick in snaps for Duke Williams, a second-year player who seems to be maturing in the defense, as well as Graham seeing some more time at safety.
