The Houston Texans' starting quarterback job is "wide open" as they begin OTAs.

Ryan Fitzpatrick, Case Keenum, T.J. Yates and rookie Tom Savage participated on Tuesday.

“These guys are good guys, they’ve been fun to coach,” Bill O’Brien said. “(Quarterbacks coach) George Godsey’s done a great job with them. And I think they’ve enjoyed learning this offense and they’re competing. It looks like there’s good chemistry in the room, which is important in the quarterback room. I’ve been impressed with these guys, the way they work at it.”
