It was a perfect Week 1 for the retooled Big 12, at least as far as the scoreboard goes. All the league’s members, including newcomers TCU and West Virginia, got off to winning starts. How they got there varied widely, and in some cases left more questions than answers. No. 4 Oklahoma scuffled its way to a 24-7 victory at UTEP, No. 22 Kansas State needed a late scoring binge to separate from stubborn Missouri State, Iowa State trailed Tulsa early and Kansas had its hands full with South Dakota State in the second half. Sooners coach Bob Stoops says there is more parity than ever in college football, so early season mismatches that became a hallmark of the opening weekend are becoming rarer.
