Can a team really give another team "their best shot" while giving other opponents less than that?
I just watched an OSU make mistake after mistake, penalties, alignment issues, not being able to run the ball, giving up on trying to run the ball ... a Perfect Storm.
We see this happen every year to top teams, which is why going 13-0 is so rare. Somehow, a team can "have a bad game" and get upset once a year, even a much better more talented team.
I view it more as a statistical event than something relating to motivation. You don't quite make that first down, you have a crucial penalty, some WR drops a ball, then the team starts pressing, which is mental, and things spiral out of control.
And Purdue has a pretty good well coached team. I hope they can keep their coach. They were a team I "had my eye on" this year. As noted, they lost 3 games that could have been wins.
