Oklahoma football: Sooners are solid No. 5 in Playoff rankings

The second week of the 2017 College Football Playoff rankings remained unchanged, but it set up a classic Oklahoma football matchup between the No. 5 Sooners and No. 6 TCU this weekend.

The Sooners retained the No. 5 position after its 62-52 shootout victory over previously No. 11 Oklahoma State. With losses by Ohio State and Penn State, however, TCU advanced two spots to No. 6, setting up the game of the weekend in college football between the co-leaders in the Big 12 Conference.

Ohio State and Penn State both dropped seven spots, to 13th and 14th, respectively, after losing last weekend. That was the biggest movement in the Week 2 College Football Playoff rankings.

Iowa State out of the Big 12 also had a big fall, declining six positions, to No. 21 from No. 15, after a four-point loss at West Virginia.

Georgia remained No. 1 after a two touchdown win over South Carolina, but the undefeated Bulldogs have a big test this weekend on the road at No. 10 Auburn. Alabama, Notre Dame and Clemson round out the top four teams in the Playoff rankings with three games to go in the regular season.

Three of the top four teams in this week’s Playoff rankings all have significant challenges this weekend. Alabama goes on the road to take on No. 16 Mississippi State, and No, 3 Notre Dame squares off against No. 7 and undefeated Miami at Miami.

We could be seeing a major shakeup in the Playoff rankings after this weekend, or it could solidify the top five spots with just two more weeks remaining in the regular season. Chances are, we will see some change, the extent of which remains to be determined.

Besides Oklahoma and TCU, Oklahoma State (15) and Iowa State (15) are the only Big 12 teams in the College Football Playoff Top 25 this week.
