Why do you think that, Matt?
He was found guilty on five felonies: “ A disorderly conduct charge for a false crime report is a class 4 felony in Illinois, each punishable by up to three years in prison and a $25,000 fine.”

Most serve their sentence concurrently, not consecutively. Additionally, the asshole lied all the way through the trial about his guilt. He should have both an obstruction and perjury charge thrown at him too…and I expect that would happen if you desire comes true; that he gets a walk.
…but I’m not a lawyer. I do make bets though and I’m betting he get the three years and maximum fine of $125K.
