After edging out BYU at home, 17-14, last week and beating Stanford 20-13 in overtime the week before, the No. 5 Fighting Irish (7-0) have kept their unbeaten record intact thanks in large part to their stifling defense, which is second in the nation in points allowed, giving up only 9.4 points per game.
The No. 8 Sooners (5-1, 3-1 in the Big 12) enter Saturday night's showdown on a roll, winning three straight games by respective scores of 41-20 over Kansas State, 63-21 over Texas, and, last week, 52-7 over Kansas. Their 44.7 points per game average this season ranks fifth-best nationally.
According to OddsShark, the high-powered Sooners opened the week as 10-point favorites at home. The line has only gotten higher, though, as it currently favors Oklahoma by 11½ points. The over/under total for combined points is presently at 47½.
Kickoff is set for 7 p.m. CT at Oklahoma Memorial Stadium, and the game will be televised on ABC.
