Big fan of your inside info, so take the rest FWIW, one person's opinion...
I am a believer in probability analysis. Reality is not binary, there are lots of possible outcomes. There is no doubt that if you ran a multivariate model that pitted us against Bama several million times using, we would win some of those games. They aren't invulnerable. Maybe we'd even win a sizeable minority. My gut tells me about 10-25% of the time, or roughly 1 in 5/6. Most people think I'm the one with O&G glasses when I say that.
But there is so much hyperbole in what you wrote. King is not a Heisman candidate. He's an MVP type kid for Miami, no doubt. I love his leadership and think he changed our program fundamentally for the better. But he's not at Lamar Jackson's level. Zion and Mallory have shown nothing of the talent everyone is talking about. Brad Kaaya was a projected first rounder, too, at one point. You're projecting but there's no evidence to back it up. Our defense is "no joke", I agree. But that doesn't make it capable of stopping that Bama OL. We lost our two best players at DE and have no evidence the guys behind them are ready to step up Game 1.
I can see us surprising Bama by staying close then having a couple momentum plays get us a W late in the fourth. I can also see us getting beaten by 4 touchdowns because they exploit weaknesses in Manny's defense. There's a reason we're 2.5 TD underdogs.
We'll know really quickly which outcome is most likely. Just watch how our OL performs when we need a first down, and our DL performs when we need to stop them from getting a first down. If they can move us 2-3 yards at will, we're in real trouble. If you're right and we can go punch for punch physically across the line, we have a shot. ... Oh, and our linebackers actually need to be able to outrun the 330' guards who are trying to block them out of outside zone plays, or swim through them in inside power plays.
