A mighty Pac-12 contest is on tap Saturday, when the Oregon Ducks host the Stanford Cardinal at 8 p.m. ET.

This line has changed dramatically, with Stanford opening as a 2.5-point underdog but is now favored by 2.5. The Over-Under, or total number of points Vegas thinks will be scored, is 59.

Before picking a side, you need to hear what SportsLine expert Emory Hunt has to say. Hunt is the co-founder of Gameplan, which has been supplying analysis of all levels of football since 2007, and closed out the 2016 college season on a 53-33 tear.

Moreover, Hunt has been locked in on the Cardinal. He's an insane 7-1 in spread picks for or against Stanford, and just locked in a strong pick for Saturday.

We can tell you he's leaning toward the Under, but his much stronger play is on the spread. He has identified a crucial X-factor that makes one side of the spread a must-back.
