Texans coach Gary Kubiak is among those that believe Case Keenum has a future in the NFL. Keenum ended his college career as the all-time leading passing in NCAA history, throwing for 19,217 yards and 155 touchdowns in his 57-game career at the University of Houston. Despite the production, Keenum's size and career spent in a spread offense contributed to him not being selected in the 2012 NFL Draft. Keenum signed with the Texans as an undrafted free agent. "It's interesting because for him to go play under center -- he'd never done it -- that hasn't been a problem at all," Kubiak said during last week's OTAs. "Now, it's just kind of getting used to playing under there from a standpoint off seeing things and verbiage. There's a lot of verbiage in our offense and I don’t think there was much at Houston, if I'm right, so he's having to adjust to that. He's very smart. He's a diligent worker, and that's all you can ask for. "He's well on his way to learning what he's doing, so I'm very pleased. I'm excited to work with him. I think he's got a future. We just got to take it a day at a time."
