Welcome to Before The Snap, For The Win’s college football show where we’ll break down the sport’s trending storylines, examine each week’s biggest matchups and track the College Football Playoff and Heisman Trophy races.

Yes, it is only Week 4, but when College Football Playoff hopefuls play ranked opponents early on, there are playoff implications for the winners and losers. And after Week 3 didn’t have any ranked opponents playing each other, we’re back at it in Week 4.

Let’s break it down.

No. 11/10 Michigan (2-0) at No. 13/14 Wisconsin (2-0)

Both teams are coming off early bye weeks ahead of this matchup in Madison, but Michigan needed the timeout more. The Wolverines barely snuck away with a double-overtime win a couple weeks ago against a good Army team, and some put coach Jim Harbaugh on the hot seat after that game, which featured multiple coaching missteps.

The Wolverines didn’t look great on both sides of the ball. Their offensive woes and quarterback struggles with Shea Patterson were still present, despite first-year offensive coordinator Josh Gattis coming in. On the other side, Michigan’s defense is still No. 7 in the nation, but Army’s run-heavy offense still put up 200 yards and helped the Black Knights stay in the game.

This game against a formidable Wisconsin will prove whether or not Michigan worked out its issues or if it never should have been in the playoff conversation to being with.

For the Badgers, Michigan is their first real test of the 2019 season. They opened the season against South Florida and Central Michigan and walked away with shutouts in both.

Running back and Heisman Trophy candidate Jonathan Taylor is a beast and one of the best players in the country. He had more than 100 rushing yards in Wisconsin’s first two games and combined for five touchdowns on the ground. But his receiving game is helping buttress his Heisman argument. In two games, he’s combined for five catches, 65 yards and three touchdowns.

As for Wisconsin’s defense, it’s ranked No. 1 nationally, which makes sense when it’s had two shutouts. So how it handles a ranked conference opponent should serve as a better measuring stick.

The Badgers are a slight 3.5-point favorite, and a win could help set them up to be a dark-horse playoff candidate — though they’d need to make it to and win the Big Ten championship game. Currently, Michigan has a 1 percent chance to make the playoff after opening the season with a 41 percent chance — Wisconsin is at 13 percent — so a win here would keep whatever playoff hopes the Wolverines still have left alive.

No. 7/7 Notre Dame (2-0) at No. 3/3 Georgia (3-0)

The Fighting Irish need this win if they want to have a realistic shot to return to the College Football Playoff. But according to ESPN’s Football Power Index, this is actually their only game of the regular season they’re not favored to win.

Working against their playoff argument is not being in a conference and, therefore, not having a conference title game to potentially lose. So if they have a loss on their record, they’ll need chaos in a couple Power 5 conferences and some multiple-loss conference champs to stay in the playoff conversation. Plus, this isn’t their only tough matchup of the season with a game on the road against Michigan in late October.

They made it to the playoff last year with an undefeated — and easier — schedule, and took a spot that many argued belonged to one-loss Georgia instead. The lingering emotions from that will surely play a factor for fans Saturday night, but it helps Bulldogs fans that their team is a solid 14.5-point favorite.

What Notre Dame lacks in a strong schedule and brutal conference Georgia has. The SEC currently has five teams in the top-10, Georgia included, and the Bulldogs face Auburn and Florida in November, and could play Alabama in the SEC title game again. With all that and an offense that’s No. 6 in the country, Georgia could survive a good nonconference loss and still have a shot at the playoff if it wins out.

Other games with potential College Football Playoff implications include…

No. 8/9 Auburn (3-0) at No. 17/15 Texas A&M (2-1) — 3:30 p.m. ET, CBS

Both teams have brutal SEC schedules, and Texas A&M’s loss to top-ranked Clemson in Week 2 isn’t great. But a win here for the Aggies helps, should they be able to upset Alabama, Georgia and LSU later on.

Auburn and true freshman quarterback Bo Nix jumped into the playoff conversation as a serious contender after beating Oregon in Week 1. But to have a shot at the playoff, they need to stay undefeated as long as possible with games against Florida, LSU, Georgia and Alabama ahead of them. If the Tigers can manage to come away with only one loss somewhere in there, they could make an argument. A trip to the SEC championship game would help too.

Oklahoma State (3-0) at No. 12 Texas (2-1) — 7:30 p.m. ET, ABC

Texas cannot lose another game if it wants to make the playoff, which has never invited a two-loss team to dance. It’s only 6-point favorite in Austin, and the Cowboys are a little more balanced on offense. But a win here for the Longhorns shouldn’t be too hard.
