Texans' Bill O'Brien takes offensive play-calling duties from George Godsey

— -- HOUSTON --? Texans?head coach Bill O'Brien will now call plays on offense after taking those duties away from offensive coordinator George Godsey, a source told ESPN's Adam Schefter, confirming multiple reports.

O'Brien called plays during his first season with the team in 2014, but gave the duty to Godsey last year.

The Texans added offense this offseason, signing quarterback Brock Osweiler, running back Lamar Miller and drafting wide receiver Will Fuller in the first round.

Through three games, the Texans, coming off a 27-0 loss to the New England Patriots, have scored only three touchdowns. Houston has also struggled in the red zone, scoring one touchdown in seven tries this season.

After the loss to the Patriots, O'Brien said he thought the coaching staff had a good plan coming in, but the offense did not execute well.?

"We really have to go back as a coaching staff and really look at what we did, learn from it, and try to fix it," O'Brien said. "We really need to put our heads together and get after it and get better for the next game, no doubt about it."

The Texans next play the? Tennessee Titans, with whom they are tied with an NFL-low 42 points this season. Houston ranks 24th in the league in total offense.
