ok let's recap those 3 games that oregon "laid an egg" in
natl championship - lost 22-19 to #1 nfl draft pick cam newton averaging 6.2 yds per play to auburns 6.1 yds per play.
rose bowl vs ohio st - lost 26-17 averaging 4.9 yds per play vs ohio st 4.7 yds per play.
boise st game - lost 19-8 only averaging 3.5 yds per play to boises 4.1.
so 2 out of those 3 games (and 3 out of 4 if you include this year's lsu game) oregon had MORE yards per play than their opponent. kind of defeats your argument that their offense only works against "fake" defenses instead of real ones (not sure what a fake defense is unless they are using smoke and mirrors instead of 11 players).
i guess "laying an egg" is losing a national championship game on a last second field goal, and outgaining every opponent including your close losses.
