The Buffalo Bills are officially beginning their interview process for prospective head coaches this week. According to Jay Glazer of Fox Sports via his Twitter account, the Bills brass are flying to Minnesota either today (Wednesday) or Thursday to meet with Minnesota defensive coordinator Leslie Frazier. According to sources, Pat Moran of BuffaloSportsDaily.com is reporting that the Bills will meet with the San Diego Chargers defensive coordinator Ron Rivera as well before the week ends. These interviews are taking place with these two candidates this week because both of these teams are on a bye week before the second round of the playoffs.
