Here are The Post’s college football rankings following Week 4:

1. Georgia (3-0) (Last week:1)

Saturday at Alabama is the first major test in what is a minefield the rest of the way for the Bulldogs. Trips to Texas (Oct. 19) and Ole Miss (Nov. 9), along with a visit from Tennessee (Nov. 16) loom.

2. Texas (4-0) (2)

Arch Manning delivered an uneven performance in his first start, throwing for 258 yards and two touchdowns, but also was intercepted twice in a 51-3 waxing of UL Monroe. Quinn Ewers isn’t getting Wally Pipp-ed.

3. Ohio State (3-0) (3)

It took until the final week of September for Ohio State to play a non-cupcake. Michigan State is far from a contender, but compared to the Buckeyes’ first three opponents — Akron, Western Michigan and Marshall — the Spartans are a juggernaut.

4. Alabama (3-0) (4)

The Crimson Tide are a 1.5-point underdog Saturday against Georgia. That would mark the first time Alabama has been a home underdog since 2007 against LSU. New coach Kalen DeBoer is sure to play the no-respect card this week.

5. Tennessee (4-0) (7)

The Volunteers committed two turnovers on the road against a top-15 opponent and still won by double figures. They looked like a legit title contender in their 10-point win over Oklahoma and should be undefeated when Alabama comes to Knoxville on Oct. 19.

6. Ole Miss (4-0) (5)

Finally, we will get a real read on the Rebels, after four blowouts over made-to-order patsies. The SEC schedule begins for Ole Miss against Kentucky on Saturday.

7. Oregon (3-0) (6)

It’s all about being ready for Ohio State on Oct. 12. Oregon’s next two opponents, UCLA and Michigan State, are nothing more than tune-ups.

8. Utah (4-0) (NR)

Our preseason pick in the Big 12 looks like the class of the conference. It won at Oklahoma State despite missing starting quarterback Cam Rising (right hand) thanks to a stingy defense and running game that amassed 249 yards on the ground.

9. Penn State (3-0) (8)

I’ll admit it: I have no idea what to make of Penn State. A Charmin-soft early schedule hasn’t revealed much. Surprising Illinois by far will be the Nittany Lions’ toughest opponent.

10. Missouri (4-0) (10)

Missouri celebrated like it won the SEC when it survived Vanderbilt at home in overtime. The Tigers, an incredibly soft 4-0, are pretenders.

Dropped out: USC (2-1)

Heisman Watch (in alphabetical order)

QB Jaxson Dart, Ole Miss

Another big Saturday for Dart in what amounted to a pseudo-scrimmage: 382 yards passing and four touchdowns against Georgia Southern.

WR/CB Travis Hunter, Colorado

Again, Hunter did it all for Colorado on Saturday, catching seven passes for 130 yards and forcing the game-sealing fumble at the goal line in overtime.

RB Kaleb Johnson, Iowa

The nation’s leading rusher is on pace to set a single-season high in his next game. He already has run for 685 yards and nine touchdowns, keying Iowa’s 4-0 start. Up next: A trip to Columbus in two weeks.

QB Jalen Milroe, Alabama

Yes, it’s early. It’s still September. It doesn’t matter. Saturday against Georgia is one of those games that Milroe can make an early Heisman statement.

QB Cam Ward, Miami

Miami’s “alpha leader,” as coach Mario Cristobal calls him, continued his dominance in a blowout of South Florida with 404 yards through the air and three scores. There hasn’t been a more impactful transfer.
