BOULDER, Colo. (AP) -- The Colorado Buffaloes want to see Marcus Mariota play a full game because at least that would mean they're still hanging around.
The sophomore quarterback operates the fast-paced offense of No. 2 Oregon with such efficiency that he's only played four complete games in his career - and none this season.
Usually, Mariota's chilling on the sideline for the fourth quarter after dismantling defenses. The Ducks (4-0, 1-0 Pac-12) are averaging nearly 600 yards of total offense and beating teams by an average of almost 52 points. Oregon is a 39-point favorite against the Buffaloes (2-1, 0-1) on Saturday.
