No official writeup on the Music City Bowl as I've held off on allowing bias to seep in on Illini games. Here's my take on it.
Both teams will be missing guys. It looks like Tennessee will be hit harder than Illinois since Chris Brazzell will be missing as well as CB Colton Hood, pass rusher Joshua Josephs and LB Arion Carter, but as far as I can tell it's only those 4. Illinois is missing big ones. LT JC Davis, who is their best offensive lineman and LB Gabe Jacas who led the Big Ten in sacks in the regular season are opting out. They'll both be drafted. Jacas is a stud, but I think Davis is the bigger loss. Rather than upset continuity on the rest of the line, they are keeping everything intact and starting Nathan Knapik at LT, who has taken a grand total of 7 snaps on the year after transferring from Idaho, and he hardly played there either. Maybe the Illinois staff knows something about him, but that is a major risk to take against a pass rush that can get to the QB. Even with Davis, the Illinois OL struggled with pressure. Tennessee's defense hasn't been very good and they played about as weak a schedule as you can in the SEC, so Illinois will probably be able to move the ball on them, but they'll get some negative plays for sure. Illinois has had a hard time stopping any passing offenses with pulse this year, and Tennessee qualifies as that for sure even without Brazzell. I should also mention that starting safety Matthew Bailey had shoulder surgery so he is also out, but they do have some depth back there.
Ultimately I do like the Illini's mindset. They are motivated and most of their guys will be playing. Tennessee I assume will be up for it also to some extent, but I'm not sure they care much about playing the Illini. Both offenses should have the edge, but I don't think the quick passing game is a good matchup for the Illini and I think the Vols will have a major scheme advantage with Heupel v Aaron Henry, Illinois DC. Illini will have some confidence because they beat a significantly better SEC team last year in South Carolina, but I don't think this defense has it in them to get consistent stops. Altmyer will have to be at his best in order for Illinois to win, and I think he can do that, but I still think the Vols might have too much offensively for a consistently shaky Illini defense here.
