January is when it all changed for this season and when the admins starting thinking seriously of replacing Berry.
The ASU weekend was turbulent and when the tension between Berry & Jackson kind of overflowed...rumor is that they almost came to blows.
Then the horrible home weekend against WMU.
Then the following weekend when the "Jammer incident" occurred during the bye week.
The admins started hearing about these issues from players, staff, and team personnel.
Players were not happy with how Berry handled the Jammer issue...Dane wanted to handle it in a different manner that aligned with what the players wanted as well.
Berry is a great guy, no one is stating otherwise. I think he got taken advantage of a bit with that and he couldn't make the tough choices, especially with this year's senior class, their playing time & roles, and the Jammer issue.
By the time the season ended, the decision to replace Berry had already been made and had been in process for at least a month or more.
