WHITE SULPHUR SPRINGS, W.Va. — After reviewing the film from the Houston Texans’ preseason opener, coach Bill O’Brien said he was impressed by the poise that rookie quarterback Deshaun Watson showed in his NFL debut.

“Something that’s impressed me from really the time that I met him is really his overall poise,” O’Brien said. “He’s a very poised guy. He plays the game in a calm way. Obviously, nothing’s too big for him. He’s been in big games. For his first NFL game, I’m sure he was slightly nervous, but it didn’t show.”

In Wednesday night’s 27-17 preseason loss to the Carolina Panthers, Watson was 15-of-25 passing for 179 yards. He also had three carries for 24 yards and a rushing touchdown.
