Illinois vs Tennessee: Preview and best bets for Music City Bowl
By Chris Wright
Published:
The B1G has bigger games this week. Much bigger. But it’ll welcome any opportunity to knock off an SEC team — especially in that team’s home state.
Such is the backdrop for Illinois’ clash with Tennessee in the Music City Bowl in Nashville. Kickoff is at 5:30 pm (ET), Tuesday in Nashville (ESPN).
These teams have never met, but that doesn’t mean they are strangers on a first date.
Before landing at Illinois in 2021, Bret Bielema coached 5 seasons at Arkansas, so he is well-versed with SEC football. He’s also 1-0 vs. the Vols — even though that 24-20 victory in Knoxville in 2015 won’t matter much this time.
Opt-outs are an issue on both sidelines. Illinois will be without All-B1G left tackle JC Davis, among others. Tennessee is down 5 starters preparing for the NFL Draft, including leading receiver Chris Brazzell II.
Tennessee opened as a 6.5-point favorite at DraftKings Sportsbook, but the line has moved all the way down to 2.5 on Dec. 29.
Can the underdog Fighting Illini silence what is expected to be a Vols-heavy crowd in Nashville?
Illinois vs Tennessee Betting Analysis & Predictions
The evolving landscape has created a compelling betting scenario, particularly for those looking to support the Fighting Illini. Tennessee’s player opt-outs have fundamentally altered the competitive balance, with key contributors on both sides choosing to sit out. That’s why Illinois has moved from a significant underdog into a live betting proposition with legitimate upset potential.
Illinois has demonstrated resilience throughout its season, showing particular strength in close games where it has covered ATS when playing as underdogs of 3+ points. The Fighting Illini’s offensive efficiency under QB Luke Altmyer has been consistent while maintaining ball security with a positive turnover differential. Their ground game provides the foundation for controlling game tempo and keeping Tennessee’s offense off the field.
Tennessee’s season totals are impressive, but, again, that was at full strength. On defense, the Vols have allowed big plays consistently, and with key defensive opt-outs, Illinois should find more success moving the ball than their season averages suggest. The Fighting Illini are strong ATS in recent games following a victory, indicating strong momentum heading into the Music City Bowl. It doesn’t hurt that Bielema has won 5 bowl games as a head coach, either, including last year’s Citrus Bowl over another SEC team, South Carolina.
The game total appears inflated given the circumstances. Illinois’ methodical offensive approach combined with Tennessee’s defensive absences suggests a contest that stays closer to the 50s range rather than approaching the high 60s. The Under has hit in a majority of public bets, but the value lies with Illinois fans backing their team’s ability to keep this game competitive while staying below the posted number.
Best bet: Illinois +2.5 (-108) at DraftKings Sportsbook on Dec. 29, 2025.
Secondary Play: Under 61.5 (-110) at Bet365 Sportsbook on Dec. 29, 2025

- Game Total: Public bettors are heavily favoring the Under, with 82.97% of all bets and 85.7% of the handle on the game staying below 61.5.

Matchup Analysis: Finding Illinois’ path to success
Can Illinois slow down Tennessee’s tempo? That’s the key to the game.
“For sure, offensively, just super explosive offense. Obviously, play with great tempo. I’ve never played against Coach Heupel, but have been very, very impressed with his, not just his game calls, but the schematics behind it, but also the use of the clock,” Bielema told reporters ahead of the Music City Bowl. “Very explosive group overall. It was funny, a couple years ago I was at a Nike clinic. I was there to speak, but I got there a couple hours ahead of time. He was speaking so I went and sat in that meeting and really kind of heard him for the first time talk about his offensive philosophy. A lot of what we saw carries over.”
Tennessee’s offensive numbers appear dominant, but the key lies in field position and defensive execution. Illinois actually holds a slight advantage in points allowed per game, suggesting its defense has been more consistent throughout the season. The Fighting Illini’s pass defense ranks well nationally, compared to Tennessee’s unit, indicating Illinois might be better equipped to limit explosive passing plays. It helps that the Vols won’t have Brazzell.
Altmyer’s pocket presence and decision-making have been crucial to Illinois’ success, completing passes at a reliable clip while avoiding costly turnovers. His matchup against a potentially depleted Tennessee secondary creates the best player prop opportunity in this game. The Volunteers’ pass defense has shown vulnerability to consistent underneath routes, exactly the type of methodical attack Altmyer employs effectively.
