Also, the 1 seed is rarely as exceptional as Tennessee is, so I'd put those odds closer to 80% than 70% to make Omaha.

And then you add Kurt Angle to the mix...
It's making the National Championship Series that is so dang difficult. Think about the regional setup: splitting isn't good enough, 2-2 gets you kicked out. You have to go 3-1 or 3-0 to advance. This isn't as bad at the regional level because some of those 4 seed teams are pretty mediocre, especially the 4 seed if you're really high up the rankings. 3 seeds generally aren't crazy tough either.
But Omaha? It's the exact same setup: 4 teams in, 1 team advances. But instead of facing a pretty balanced group of teams, you've got 3 other teams that are hot as heck, made it to Omaha.
It's weird that it's disproportionally hard to make the National Championship compared to winning it, but that's how it is. If Tennessee survives the Omaha mini-regional, our chances of winning a natty will soar.
If Omaha was a bracket of best-of-3 series, I think our odds would be +300 or +250 right now instead of +400.
