Lovie is also the first AA coach in Illini history...that is a big deal and if you know anything at all about the Chicago Public Schools (and private) it could be a huge part in recruiting.
How much D1 talent is in the Chicago area vs. the rather fertile grounds in Ohio and Michigan? I suspect enough to complete better with Iowa, Nebraska, etc but not tOSU. Maybe that is OK - if Lovie can make IL relevant (even if they never make a Conf Champ Game) - winning record keeps him around at least 7 years most likely.
