Houston Texans coach Gary Kubiak “loves” Case Keenum according to several people close to him and has long been raving about the raw potential in the former un-drafted quarterback. With Matt Schaub injured and unable to play -- and already losing his grip on the starting job anyway -- Keenum could end up starting more than one game sources said with the staff having been eager to get a look at him for quite some time. Making the move from a quarterback making $15-million a season to a kid with zero NFL experience in a season that began with Super Bowl aspirations is beyond bold. And while patience has characterized Kubiak's long tenure in Houston even had Schaub lost his job due to performance alone sources said Keenum and not T.J. Yates the No. 2 quarterback on gamedays this season would have gotten the nod. Yates who won a playoff game in 2011 is seen more as a Schaub clone sources said while Keenum though lacking a big arm and experience was seen as someone who might spark the offense in different ways restore more emphasis on the boot action so fundamental to Kubiak's offense and perhaps bring a different pulse to the huddle. Keenum will be making his debut in a raucous Arrowhead Stadium against a menacing Chiefs defense but the sense within the Texans (2-4) hierarchy is anything other than panicked with the youngster under center.
