Cowboys playbook due to expand, but how much?

Oklahoma State has played it relatively safe in its first few games of the 2015 season, and it makes sense why. They've sort of treated these first few games as a preseason, akin to NFL teams gearing up for regular season action.

Texas is 1-2, but they looked formidable against Cal. The Cowboys may have to expand their playbook. But how much will offensive coordinator Mike Yurcich and company reveal?

“It's on a week-to-week basis,” Yurcich said, “depending on who you're playing; depending on what you can pull from last year's film; depending on what people are doing against your upcoming opponent.
