Tennessee Titans quarterback Will Levis gained steam in Houston

What he's saying: "I've just been really happy with the way Will has progressed," Callahan told reporters yesterday. "He's played winning football from that position, really over the last three weeks, and I'd like to see it continue."

The big picture: There is still plenty of room for improvement, Callahan said, noting Levis' skill avoiding sacks and making quick decisions.

• "I think there's another level we can get to and unlock from him."

Yes, but: The Titans are still 3-8, and Callahan acknowledged major errors that have plagued the team. For instance, Levis got sacked eight times during Sunday's game.

• "We can't give up eight sacks a game and feel like it's going to be good enough," Callahan said. "It's partly on Will, it's on the line, it's on me."
• "We can all do a better job to get that fixed."
