Texans forced to start new QB against Ravens Keenum started eight games for the Texans last year, losing all of them, before he was released in August when Ryan Mallett was acquired in a trade. When asked about returning to Houston, the folksy Texas native, who speaks with a pronounced Texas lilt, partially quoted something his former coach Art Briles, currently at Baylor, used last week during a rant after the Bears were left out of the college football playoff. Keenum was with the team when the offense was installed in training camp and hopes that will make the transition easier. Keenum threw for 1,760 yards with nine touchdowns and six interceptions last season. Lewis believes he has made a lot of progress since joining the team less than a month ago and is confident he'll be ready if he starts against the rugged Baltimore defense. O'Brien has known Lewis since he was the offensive coordinator and quarterbacks coach at Duke when Lewis was a freshman. Receiver DeAndre Hopkins said they can't worry about the problems at quarterback and just have to do what they can to make it easier for whoever starts.
