Week 4 Recap: Indiana Demolishes Illinois 63-10, Arch Manning Puts on a Show

Previews · by Rick's Picks Editorial Team

Week 4 delivered individual performances that will be remembered when Heisman ballots are filled out in December. Two quarterbacks in particular made statements that demanded national attention.

Performance of the Week: Fernando Mendoza

Indiana's Fernando Mendoza was virtually perfect against No. 9 Illinois, completing 21 of 23 passes for 267 yards and five touchdowns. Elijah Sarratt hauled in two of those scores as the Hoosiers blasted a ranked Big Ten opponent 63-10.

This wasn't a case of stat-padding against a cupcake. Illinois came in ranked 9th in the country, and Indiana dismantled them so thoroughly that the starters were resting by the middle of the third quarter.

The significance here goes beyond the box score. Mendoza's 91.3% completion rate against a ranked defense is the kind of efficiency our models weight heavily. It's not just that he threw touchdowns -- it's that he made zero critical errors against legitimate competition.

Arch Manning's Showcase

Not to be outdone, Arch Manning reminded everyone why he was the most hyped recruit of his generation. Against Sam Houston State, Manning completed 18 of 21 passes for 309 yards and three touchdowns, adding two rushing scores for good measure. Texas won 55-0 in what amounted to a two-quarter performance from their star QB.

The stat line is eye-popping, but our model applies context: Sam Houston State's defense ranked outside the top 80 nationally. Manning's efficiency was impressive, but the competition level means we temper our projections accordingly.

Prediction Model Update

Week 4's results were notable for how many favorites won by their expected margins. The top-10 teams went 8-2 relative to our projections this week, which is significantly above the historical average. When elite teams perform at this rate, it usually signals a talent gap between the top of the sport and everyone else -- and that's exactly what we're seeing in 2025.

Large favorites (20+ points) had a mixed week, with several winning comfortably (Texas, Ohio State) while others struggled to pull away. This aligns with our model's projection that public perception is undervaluing mid-tier Power 4 teams in lopsided matchups.

Vanderbilt Stays Perfect

Vanderbilt improved to 4-0, and the Diego Pavia hype train is now running at full speed. The Commodores are generating national attention, and for good reason -- they're not just winning, they're dominating opponents in ways this program hasn't done in modern history.

The Big Picture

Through four weeks, the 2025 season is shaping up to be a three-horse race at the top: Ohio State, Indiana, and Georgia. Each team has shown the combination of elite offense, stifling defense, and quarterback play needed to survive a 16-game path to a national championship.
