GameDay Kickoff: Second-chance Saturday for two top-10 teams

— -- College football fans have been spoiled this season with one fantastic weekend after another.

Don't shrug your shoulders at Week 7 -- it's second-chance Saturday.

With top-10 matchups in the Big Ten and SEC, there's plenty at stake as No. 8 Wisconsin hosts No. 2 Ohio State (8 p.m. ET, ABC) and No. 9 Tennessee hosts No. 1 Alabama. There are parallels to be drawn between the two games, as it's a chance for both Tennessee and Wisconsin to salvage their seasons with signature wins over the conference favorites.

Here's a deeper dive into those games and what they mean to the College Football Playoff race:

No. 1 Alabama at No. 9 Tennessee

Playoff impact: Tennessee gets a second chance at the best of the SEC West after losing in double overtime last week to Texas A&M. If the Vols lose their second straight, Florida is right back in the SEC East race and the Gators can win the division if they win out. The only bright spot for Tennessee in that scenario is Florida still has to play at Arkansas, and if both Florida and Tennessee finish the season with two losses, the Vols would still own the tiebreaker and win the East.

For Alabama, this is the Tide's second straight road trip after beating Arkansas last week, and the second game in a season-defining stretch that also includes Texas A&M and a road trip to LSU. The Tide still has some wiggle room and can survive a loss to the Vols -- but only if they win out, as the Aggies are undefeated right now, too.
