College football Week 4 preview: Five best games to watch this weekend

Last week, college football fans saw Arch Manning take over for an injured Quinn Ewers and lead Texas, now the No. 1-ranked team in the country, to a commanding 56-7 win over UTSA. Manning passed for 223 yards and four touchdowns, while also adding a 67-yard rushing score that gave Longhorns fans flashbacks to Vince Young. This Saturday, Manning will get his first college start when Texas faces UL Monroe at home.

We also saw Georgia, now the No. 2-ranked team in the nation, struggle to eventually beat Kentucky, 13-12. While the score line confounded some, Bulldogs coach Kirby Smart praised his team's resiliency. Smart's teams have overcome games like this in the past and there's no reason to believe they won't do the same thing this year as the opponents on their schedule get tougher.

Meanwhile, Alabama looked like a College Football Playoff contender in a 42-10 thumping of Wisconsin in Madison. Playing behind a healthy offensive line, quarterback Jalen Milroe accounted for five touchdowns and is back in the Heisman Trophy conversation.

The Week 4 slate looks just as enticing, with several matchups between top 25 opponents. 

Here are the top five games to watch this weekend:

No. 24 Illinois at No. 22 Nebraska ( Friday at 8 p.m. ET on FOX )

Nebraska will face its first ranked opponent under the lights in Lincoln on Friday night. Huskers quarterback Dylan Raiola has been sharp in his debut season. In last week's 34-3 win over Northern Iowa, Raiola completed 17 of 23 passes for 247 yards with two touchdowns and one interception. He'll have a new challenge this week, facing the best defense he's seen all year. Illinois is limiting opponents to 151.7 passing yards per game and has already totaled six interceptions
