Carmichael is scheduled to interview with the Bears on Thursday. Carmichael would be a dramatic change for the Bears as Smith is a defensive coach. The Chicago Bears will interview New Orleans Saints offensive coordinator Pete Carmichael Jr. Carmichael, 41, has served as New Orleans' offensive coordinator since 2009, but his contract was allowed to expire after this season, sources told ESPN on Thursday. Carmichael gained attention last season when he took over the play-calling duties from Sean Payton after the Saints' coach injured his leg during a game and was forced to the coaches box. The Bears are expected to hire a coach with an offensive background, given the recent struggles on that side of the ball. NFL.com reported the Bears are the first team to request permission to interview Arians.
