Growing up an Illinois fan and a Bears fan, I know all about this guy. He's a good coach for sure, even if the Bears had a miserable O-line this year. That wasn't really his fault, though, as they had very little talent.
His time at Illinois is important in that he developed some very good offensive lineman that now play in the NFL. David Diehl, Tony Pashos, Brandon Moore, Duke Preston - just to name a few. Like the article said, many more went on to sign with NFL teams. Plus, 12 all big-ten selections in his 8 years at Illinois. That's pretty darn good.
