Following injuries, starters returning, and more, there were several changes to this week's depth chart, ahead of the Bills' matchup. 

The Panthers are 4-3 and feeling good about a defense that's once again playing well. And there were plenty of questions about the particulars, in a Derrick Brown appreciation day version of the Mailbag.

The Panthers and Bills both come into Week 8 with four wins. Buffalo is coming off a bye week with the reigning MVP, but a long list of injuries as well. Get to know the Bills ahead of Sunday's matchup. 

The chemistry between Panthers' receiver Xavier Legette and quarterback Andy Dalton has resulted in two career days for the receiver, and was evident on a game-clinching play against the Jets. 

Dave Canales had high praise for Brown after he filled up a stat sheet, plus more on his running back rotation, what comes next at quarterback, and more after the win over the Jets.

Trevin Wallace had a TD-saving pass break-up against the Jets. Pre-snap, he couldn't believe Jaycee Horn was asking him to cover a receiver. Afterward, he was just thankful he had the speed to make it.

Andy Dalton replaced Young Sunday and would start against the Bills if Young can't go, but Canales said they'd continue to evaluate the quarterback this week.

The Panthers found ways to grind out a road win on a day without many big plays on offense, but finding a formula that included a big day on defense meant no one was apologizing for being 4-3.

With their sixth starting lineup in seven games, the Panthers did the job up front again, with a bunch of people who know each other well.
