Considering there is a .01% of winning, yes.
You really need help. We would have to play them 10,000 times to have an expectation of getting a win? You realize that there are never odds that bad in a football game, right?
In 10,000 games between FBS and FCS schools, FCS schools would, on average, win close to 2,000. This is because they have won over 400 games in just over 2,000 attempts. Four times FCS schools have beaten RANKED opponents. And you know that only a small fraction of the 2,000 or so games were against ranked opponents. Moreover, even if FCS and FBS teams played 10,000 times, each of which involving a ranked FBS opponent, and they still only had 20 wins, you would still be saying that an FCS school is 20 times more likely to beat Oklahoma than is UT.
I know you're just pulling a number out of your ass, and I know you have a schtick to play up to here, but at least try a little bit to be objective and rational. A HS team has a .01 chance of beating Oklahoma.
Edit: In the interest of full-disclosure, I was being a little sloppy. The point about FCS schools being 20 times more likely of beating OK than UT on your account is assuming that Oklahoma is to the average top 25 team as UT is to the average FCS team. And it is ignoring the fact that FCS schools won 4 games in far fewer than 2,000 attempts. I obviously think that this is wrong, and that UT is much closer to OK than to an FCS school. But, that's all I need to show you that you're completely insane.
