HOUSTON (AP) Texas Tech has the nation's top offense, and it's trying to keep it that way as the schedule gets tougher.

The Red Raiders (2-0) have averaged 54 points and 620.5 yards through their first two games, but things will get more challenging in Big 12 play. With Oklahoma State looming in the conference opener Sept. 30, Texas Tech faces a possible trap game when it plays at Houston (2-0) on Saturday.

"They're just trying to get better every day, they're not looking past anybody and that's what having a tough nonconference schedule will do for you," Texas Tech coach Kliff Kingsbury said. "Make sure you're focused on the first three because they're all going to be huge challenges."
