The Texans have signed quarterback Dan Orlovsky to replace Sage Rosenfels as Matt Schaub's backup. "I think the big reason here is just coach [Gary] Kubiak," Orlovsky said. "Spending time with him and [offensive coordinator Mike] Shanahan, sitting down with them and really getting to know them, not only as football coaches but as people, what they preached and what they believed in, was important to me. "I'm not stupid; I know no team is just going to say, 'Hey, you're our starting quarterback.' So why here? I feel comfortable. I feel that coach Kubiak is a coach that can push me, and I'm excited to learn under him and just get better."
