This weekend brings us a meeting between ranked Big Ten rivals, one looking to earn its first conference win and another hoping to win a second league game, as No. 19 Illinois goes on the road to Happy Valley against No. 9 Penn State in college football’s Week 5 action on Saturday night. 

Illinois already boasts a road victory against a ranked Big Ten opponent after taking down Nebraska last week and defeating a then-ranked Kansas team a few weeks ago.

Penn State is perfect through 3 games and is coming off a 56-0 domination against Kent State, embarking on the first of an expected three Big Ten games against ranked opponents this season.

What can we expect in the matchup this weekend?

Let’s turn to the SP+ prediction model to get a preview of how Penn State and Illinois compare in this Big Ten football game under the lights.

Penn State vs. Illinois score prediction

As expected, the simulations are siding more with the home team this weekend.

SP+ predicts that Penn State will defeat Illinois by a projected score of 33 to 15 and will win the game by an expected 18.6 points.

The model gives the Nittany Lions a strong 88 percent chance of outright victory in the game.

SP+ is a “tempo- and opponent-adjusted measure of college football efficiency” that attempts to predict game outcomes by measuring “the most sustainable and predictable aspects of football.”

How good is it this season? So far, the SP+ model is 105-91-1 against the spread with a 53.6 win percentage.

Computer prediction

Other analytical models also favor the Nittany Lions to take down the Fighting Illini.

That includes the College Football Power Index, a computer prediction model that uses data points from both teams to simulate games 20,000 times to pick winners.

Penn State is projected to win the game in the majority 86.3 percent of the computer’s updated simulations.

That leaves Illinois as the expected winner in the remaining 13.7 percent of sims.

Penn State is projected to be 16.9 points better than Illinois on the same field in both teams’ current composition, according to the model’s latest forecast.

Penn State is second among Big Ten teams with a 59.2 percent chance to qualify for the College Football Playoff and will win 10.2 games this season, according to the FPI’s metrics.

That model gives Illinois a 9.1 percent shot at the playoff and a win projection of 8 games.
