I think a defense and ST accounting for that many points again is quite a long shot, and building a contract around that seems like a poor decision.I saw a couple good points on this story yesterday:
1. It is unlikely the contract stipulates that the offense must average 25 PPG. Apparently the Iowa defense and special teams scored over 25% of team's touchdowns this past season.
2. Failing to reach that PPG threshold merely terminates the existing contract. It does not mean Ferentz will actually be fired.
I've seen people make that distinction about the contract as well, but I don't think this amendment gets done if he is retained regardless of meeting those stipulations. The obvious tea leaves read as an AD and booster network who can't force Kirk to do anything, but have given an ultimatum that Kirk has agreed to.
