I didn't say we would beat or be favored against every team, though. We know Ohio State and Georgia would be favored. I don't need to debate about Indiana, Oregon, Ole Miss, or Bama, because it doesn't matter. Even if we assume those six teams should be ranked ahead of Texas, that still makes Texas a top ten team. The rest are "the obvious" (to borrow your words), but just to be thorough, we beat Vandy, ousux, and aggy, and we have a better record than ND against common opponents.
Tech has no common opponents because of its incredibly weak schedule. You cannot say with a straight face that Vegas would project Tech to beat Texas. That's just reality. The same can be said for BYU.
Miami is the closest call because it has a better record and beat the only common opponent (Florida) albeit not at the swamp. If we grant that Miami should be ahead, just to be conservative, that means seven teams clearly should be ranked ahead of Texas: Ohio State, Georgia, Indiana, Oregon, Ole Miss, Alabama, Miami. The remaining teams (Vandy, ousux, aggy, ND, Tech, BYU) might have better records, but they would not be favored against Texas because Texas is a better team with better athletes, and Texas has already beaten half of them.
