And I'd say you're smoking something if you think giving up 51 points is a sign of a good team. Win or lose, you don't give up 51 points.
Sly covered the defense having short rest all the time so I won't bother, but I could easily argue a good team doesn't get taken into 3 OT at home against a shitty Big East team in Pitt that lost to Youngstown State. We could play this all day.
ND has had a MUCH tougher schedule then Oregon thusfar. Arkansas State, Fresno State, Tennessee Tech, #22 Arizona, Washington St, #23 Washington, Arizona St, Colorado, #17 USC. 3 ranked opponents (22, 23, 17). And Tennessee Tech is a 3-7 FCS team. How can you even count that as a non-exhibition game is beyond me.
Notre Dame has played Navy, Purdue, #10 Michigan St, #18 Michigan, Miami, #17 Stanford, BYU, #8 Oklahoma, Pittsburgh, BC. 4 ranked opponents (2 in the top 10).
ND's schedule is tougher, but many of those teams aren't worth their salt. Purdue/Navy/MSU/Miami/BYU/Pitt/BC are all mid level Pac-12 teams at best. UM is slightly above average but are in a downed Big 10. Stanford and OU are solid wins, though. Oregon has some clear cupcakes (Arkansas St/Fresno St/Wazzu/Colorado/Cal) but Oregon still has some pretty strong wins against USC, Washington, and Arizona. Not as good as ND, but it hasn't been 10 cupcakes in a row. And as you stated in the next paragraph, assuming both go undefeated, Oregon's schedule will match up very fairly with NDs since they'd potentially add a ranked Stanford, Oregon State, and USC or UCLA (compared to ND just putting on USC once).
Oh, and Oregons QB just got hurt. Hopefully it isn't serious. But if it is, that's a massive blow, and going undefeated seems even less likely.
Don't worry, his 27-34 for 377 statline looked pretty good.
