Nebraska redshirt freshman quarterback Taylor Martinez showed dazzling speed in a 242-yard, four-TD rushing performance against Kansas State. On Saturday he goes up against the most athletic defense he's faced yet, that of Texas. Another big day might boost Martinez near the top of the Heisman race.... Undefeated Michigan State (6--0) is getting it done with a classic Big Ten smashmouth offense. Running backs Edwin Baker and La'Veon Bell are averaging a combined 205.3 yards a game.... No. 4 TCU may hold a top five ranking, but watch out for Mountain West rival Utah. The No. 11 Utes (5--0) destroyed Iowa State 68--27, amassing a staggering 1,026 yards in total offense and kickoff, punt and interception returns.
