I'm assuming you don't know much about Tim Beckman.
Beckman was 4-20 in the BT in three years and was fired a week before the season when an internal investigation found he was forcing players to play while injured. And, that says NOTHING about his atrocious recruiting.
And, then there is Bill Cubit who followed Beckman.
I'm not sure you understand the dumpster fire Lovie inherited at Illinois.
He's turning over the roster at an incredible pace...

which means he's playing the youngest team in the country which started 15 TRUE freshmen, played 22 TRUE freshman and had 60 cumulative starts from true freshmen this season...
