I get all that, we've discussed that before.
But if there's something that outmanned teams do in order to 'sneak' closer to upset victories, then if the favored programs do those same things, it will always negate any advantage sought out by the underdog.
There you go. Your use of the term "always" suggests you completely missed the variance point of my argument.
I've used the 2018 Purdue upset of Ohio State, where they won in a 49-20 rout, as an example of this. Ohio State was running a high-variance spread offense.
- Ohio State slightly outgained Purdue.
- Ohio State had more first downs than Purdue.
- Ohio State had a higher 3rd down conversion rate than Purdue.
- Ohio State slightly edged Purdue in TOP.
- Ohio State ran 98 offensive plays to Purdue's 72.
Ohio State couldn't run the ball against Purdue's weak defense. They averaged 3 ypc, and only ran the ball 25 times against 73 pass attempts.
So what was the difference? For all that offensive success, they bogged down in the red zone and then were only 2/3 on their FG attempts. Purdue hit on big plays, so despite having a worse offense against a better defense, they got lucky when it mattered.
It's like boxing. If you're outmatched, you need to throw some haymakers and pray they connect, because if you fight a technical battle against a technician, they'll slowly wear you down.
In this case, both the outmanned and the favorite were throwing haymakers, except it was only the outmanned fighter that was landing them.
