Itās more likely to be a blessing for the Illini, as theyāve upgraded their offensive weaponry beyond just quarterback-turned-wide receiver Isaiah Williams and running back Chase Brown.

However, the below-average offensive output from the 2021 Illini was not enough to justify keeping offensive coordinator Tony Petersen.
