http://msn.foxsports.com/nfl/story/5896698 22. Houston Former Denver offensive coordinator Gary Kubiak is the new head coach. Kubiak was John Elway's backup for nine years, and after retiring as a player, he became an assistant in Denver. His experience as a player and a coach help him understand how quarterbacks develop. His job is to get quarterback David Carr playing at the level the Texans expected of him when he was the first pick in the 2002 draft. Kubiak hired his fellow Denver assistant, Troy Calhoun, as offensive coordinator. He also hired Mike Shanahan's 26-year-old son, Kyle, as wide receivers coach. Defensive coordinator Richard Smith and defensive line coach Bob Karmelowicz have spent a lot of time in training camp trying to organize the line in a way that capitalizes on Mario Williams' considerable talents.
