Round 1 seems really straightforward.
But Alabama / cal and Kentucky / MSU have potential to be nail biters in round 2 (and to a lesser extent Georgia / missouri), then UCLA / Utah is a rough fight in nationals should things play out normally. Cal/UCLA/Utah feels very tight for that fourth spot, and that's not even counting cal has to get through Alabama first at home.
Anything else I'm missing? I like an LSU repeat this year, gotta be the most impressive roster and they've delivered all season.
