Sean McDermott has agreed to become the next coach of the Bills, Jason La Canfora of CBS Sports reports via John Breech of CBS Sports
. The 42-year-old coach will take over in Buffalo after spending the past six seasons as the defensive coordinator for the Carolina Panthers.
The hiring of McDermott ends a 15-day process that started when Bills offensive coordinator Anthony Lynn was named interim coach after Ryan's firing on Dec. 27. At first, Lynn was believed to be a front-runner for the job, but the Bills decided to go in a different direction.
Instead of going with an offensive mind like Lynn's, Buffalo once again turned to a defensive mind.
During six seasons in Carolina, McDermott led a defense that finished in the NFL's top-10 three times. That total includes a dominating 2015 season where the Panthers' defense helped pave the way for a Super Bowl run with a unit that ranked sixth overall.
