Offense: Iowa State’s run game has been stagnant for the entirety of conference play. Part of that may be due to the injuries in the backfield, so coming off a bye week, I’ll select running back Jirehl Brock as my player to watch. Oklahoma started the season terrific on the defensive side of the ball, but they’ve drastically fallen on that side of the ball against the Big 12. They’ve given up almost 275 yards per game on the ground in their four conference games, the lowest of which was their most recent outing in Lawrence when they gave up 165.
