IS ZOOK A GOOD COACH?

The jury is still out on the Illini football coach.
I felt the Illini got the best coach available when they hired Ron Zook. I was comfortable with him until the half of the California game.Since then, even understanding the talent level is low, I having my doubts about his coaching ability.
1. Young inexperienced teams generally make noticeable improvement during the season. (I think the Illini are worse.)
2. Young teams make fewer mistakes as they season progresses (Not the Illini, and it reflects on the coaching.)
3. Listed as a great recruiter upon arrival, I fail to see it. (Few outstanding recruits at Illinois and the Florida team he recruited lost their third game last week.)
4. Perhaps a minor point, but his sideline demeanor is not that of a confident coach. (His constant pacing looks like a man almost out of control. How can the players display control with that example.)
5. His teams play worse in the second half than the first half. (Coaches look bad when their teams fall apart.)I hope I am wrong. Zooks seems like a man who gives it all. I hope he can turn it around and I willing to wait a couple of years for improvement. I must admit I have my doubts that the “Zook era” will ever be rated as a success.
