The rest of the top 10: No. 1 Georgia, No. 3 Alabama - both 9-0 - the third-ranked Irish, No. 4 Clemson and No. 5 Oklahoma and No. 6 TCU, all of whom are 8-1.

"People still think teams qualify for this if they win a conference championship - that's why they get so frustrated and so emotional", Herbstreit said.

Rounding out the top 10 in this week's College Football Playoff poll are No. 7 Miami, No. 8 Wisconsin, No. 9 Washington and No. 10 Auburn. The Crimson Tide jumped on LSU in the first half, taking a 14-0 lead and riding the fast start to a 24-10 victory.

No change in the top four after that group takes care of business over this past weekend.

That's a possibility college football analyst Kirk Herbstreit discussed during the College Football Playoff rankings show on ESPN.

"What really matters is how you play the rest of the season, how you focus the rest of the season and how you stay focused the rest of the season".

It wouldn't be a stretch for the selection committee to keep the Badgers out of the playoff if other top teams keep winning, according to Herbstreit.

Holding the fifth spot again this week is Oklahoma (8-1). Oklahoma 6. TCU 7. UCF sat at No. 18, its same ranking from last week, and four spots ahead of Memphis (8-1), whose lone loss came to UCF. The College Football Playoff selection committee ranked the Tigers No. 10.

Alabama (9-0, 6-0 SEC) is the only team to make the playoff in each of its first three seasons.

Especially, how far will #9 Wisconsin climb after losses by Big Ten stablemates #6 Ohio State and #7 Penn State and #8 Texas Christian's decisive but unspectacular home win over Texas? The Hurricanes will be in the top five next week with a win on Saturday.
