The San Francisco 49ers slate of opponents for the 2019 season has been finalized, but five of them fired their head coaches early in the offseason. Three of those teams announced replacements on Tuesday. The Cardinals hired former Texas Tech coach Kliff Kingsbury to replace Steve Wilks, the Packers hired Titans offensive coordinator Matt LaFleur to replace Mike McCarthy, and the Buccaneers hired former Cardinals head coach Bruce Arians to replace Dirk Koetter. The Bengals are still in the process of hiring a replacement for Marvin Lewis, and the Browns are looking for a replacement for Hue Jackson.
