Key Storylines
- Illinois’ Resilience: After a 63-10 loss to Indiana, Illinois bounced back with a dramatic win over USC. Illinois is 4-1 on the season and showed a lot of heart to come back and get a win after an embarrassing loss to a conference rival two games ago. That bodes well for this game against a lesser Purdue squad.
- Quarterback Leadership: Luke Altmyer’s standout performance against USC included 328 passing yards and two touchdowns. His play at the quarterback position should give the Fighting Illini a significant advantage over Ryan Browne and the Boilermakers.
- Purdue’s Struggles: Purdue’s defense has been porous against quality competition. They have allowed 44.5 points per game in losses to USC and Notre Dame over their last two games. Things might not get easier for the Purdue defense facing a very good Illinois offense.
Quarterback Play
- Luke Altmyer (Illinois): Altmyer has thrown for 1,183 yards and 11 touchdowns this year. he has yet to throw an interception and will look to continue protecting the ball while making dangerous plays for the Fighting Illini.
- Ryan Browne (Purdue): Browne is a capable passer who can move the ball effectively. He has 1,036 passing yards through four games. Browne has six touchdown passes, but also has five interceptions, and has to take care of the football to keep his team’s chances of pulling an upset alive.

Final Thoughts
I would expect Illinois to win this game by double-digits on the road against Purdue. While the Boilermakers haven’t been quite as bad as they were last season, they still have a long way to go to catch up to a team like the Fighting Illini. Look for Altmyer to continue his strong start to the season and for the Illini to get a second win in a row to move to 2-1 in Big Ten play.
