ARLINGTON, Texas — Here are four of the key matchups that figure to go a long way toward deciding the Big 12 Championship Game between Oklahoma and Iowa State (11 a.m., Saturday ABC):
OU linebacker Brian Asamoah vs. Iowa State running back Breece Hall: Asamoah has quietly put together a big year for the Sooners, with a team-high 53 tackles plus four quarterback hurries, three pass breakups, five tackles for loss and 1.5 sacks. He figures to be a big key in slowing down Hall. This is strength vs. strength, with Hall leading FBS in rushing with 1,357 yards and the Sooners allowing just 88.
