Who are you calling second string?
Texas Tech lost its top rusher, Eric Stephens, two weeks ago against Texas A&M.
Oklahoma's top back, Dominique Whaley, hasn't played yet with flu-like symptoms.
Their replacements have been outstanding in the first quarter, with the Red Raiders and Sooners locked up in a 7-7 tie.
Tech's Aaron Crawford has broken a handful of tackles and has 42 yards on just four carries.
Oklahoma's Roy Finch broke off a memorable 55-yard run on the opening drive to set up Oklahoma's score. He's got 62 yards on his first four carries.
Both teams are among the deepest at running back in the Big 12. Games like tonight make you prove it. Both sides are doing it.
