This week? Neither had any competition though. They both did nicely last week . . .
At this very early date I'd single out . . :
Alabama -- though our offense is still pretty suspect at this point . . .
Ohio State -- no competition yet, so no reason to change preseason perceptions . . .
FSU -- Nice comeback win vs. Ole Miss, and it looks like they may have less competition in the ACC than I anticipated . . .
Texas? -- Looked better than their Big XII brethren so far, and no one from the Pac-12 has impressed . . .
I like Texas to take the Big 12 based on last week, but this week, I wouldn't say I was "impressed" with Texas, per se. OU, Ok State and TCU all got knocked off, Baylor hasn't faced any real competition (nor do they ever--they have an awful liking for playing Country Junior College). I pick Texas to win a weak Big 12 conference.
True, Houston and Texas A&M faced lower-division opponents, but they completely shut them out and dominated them; and did well last week. I think they're up-and-coming. Plus A&M has a bit of a history vs. Alabama.
