I am so tired of hearing the Year 7, Year 8, Year 9 blah blah blah. It's like how stupid investors and corporations think. The line can't and never will always go up. Look at Bama and Clemson right now. Did Saban and Swinney forget how to coach? Nope. But their current crop of players isn't quite as good, or maybe these guys aren't gelling as well as past teams, etc. It doesn't matter what year it is, as this isn't the NFL where you can have your franchise QB for 10+ years.
In saying that, yes there are coaching philosophies Campbell clearly needs to drop the pride on and adapt. But take our dumb rival Iowa. They could have canned Kirk several times because "Hey it's year 10 WTF?" And then they turn around and win 10+ games, go to the Big Ten Championship, etc.
