Doug Chapman wanted everyone to know Marshall can play with the big boys. Now they know.
Chapman scored three touchdowns and Marshall's defense did the rest as the No. 11 Thundering Herd completed an undefeated season by beating BYU, 21-3, on Monday in the Motor City Bowl at Pontiac, Mich.
"It was a dream come true for the whole team," Chapman said.
Chapman, who rushed for 133 yards, ran for two TDs and hooked up on a pass play with Chad Pennington for another as Marshall (13-0) remained one of three unbeaten Division I teams in the country.
"Doug stepped up," Marshall coach Bob Pruett said. "In every big ballgame we've had, Doug Chapman's done some great running."
BYU (8-4), co-champions of the Mountain West Conference, got its lone score on Owen Pochman's 28-yard field goal in the first quarter. It was all Marshall after that as the Mid-American Conference champions broke the game open with two touchdowns in a 1:44 span during the second half.
The game had been billed as a shoot-out between Pennington and BYU's Kevin Feterik.
But Pennington, who came in with 3,799 yards passing and 37 TD tosses, completed 17 of 28 passes for 207 yards with one interception.
Feterik, who passed for 3,554 yards and 25 TDs this season, could never escape the pressure from Marshall's quick defenders. He was 6 of 11 for 125 yards before being forced from the game early in the third quarter with a deep shoulder bruise.
