TUSCALOOSA, Ala. – The ball seldom hit the ground, regardless of which Alabama quarterback was throwing the passes.

The top-ranked Crimson Tide’s defense also held its third straight opponent out of the end zone.

A.J. McCarron completed 15 of 16 passes for 166 yards and four TDs in the first half and Alabama was brutally efficient in rolling to a 45-3 victory over Georgia State on Saturday.

The Tide (5-0) jumped ahead 38-0 by halftime in what might have turned into a name-your-score game against the Panthers (0-5), a first-year Football Bowl Subdivision team.

(2) OREGON 57, COLORADO 16: Marcus Mariota threw five touchdown passes and ran for two scores as Oregon brushed off some early trickery to rout the Buffaloes at Boulder, Colo.
