Since 2011, the key word for Colorado-Oregon week has been "feast," because that's what the Ducks have always done against the Buffaloes.
Oregon has defeated CU by at least 34 points in each of the last four years.
This week, the word is "hunger."
For the first time since CU (3-1) joined the Pac-12, Oregon (2-2) doesn't look like the unstoppable force it usually does, and CU doesn't look like the hapless doormat it has been.
Yet both of them have a lot to prove.
After getting trounced by Utah, 62-20, last week, Oregon has fallen out of the Associated Press Top 25 for the first time in six years.
