The interesting connection here depends on which Big Ten schools you look at...Sure, Illinois' likely 3-0 non-conference record might have started a great season...But from a business standpoint, 3-0 in bought games doesn't do a lot for the Illini bank account because the crowd in Memorial Stadium for those games generally doesn't pay for the payout to the visitor (ISU in the opener maybe, Bowling Green & UCONN not likely).
Assuming they keep the current schedule and just add one, from a potential "gate" standpoint trading the three non-con games for another Big 10 home game could be massive - since the teams the Illini don't play are Michigan, Michigan State and Penn State (or...ehhh...Maryland). Sure, strength of schedule skyrockets...I don't see the conference giving the Illini Maryland, Indiana & Rutgers in crossovers...Even if they only can put 1/3 capacity, the Illini only had about 19,000 season tickets sold by May...
A bigger issue might be the Power 5 making a move to crush the rest of the FBS...I wonder if MAC schools will be able to remain at the same level if they lose a year of bought games. School are already axeing sports...Losing bought games might force a new official level between the Power 5 and FCS...
