Not buying season tickets was not the only way Gary and Kirk could have gotten feedback, you know. Hell, as far back as the 2014 Nebraska game meltdown, I am sure that generated some negative messages to Gary and/or Kirk.
But let me ask you: How do you know when changes were made or even planned versus any particular date?
First, a the original message I replied to was about people not buying season tickets and that forcing changes. As far as other means of communication...that's outside the scope of my post, making it a strawman.
As far as how do I know when changes were planned? Well, first, I have a source inside the program (no, I'm not going to "out" them). Second, KF said he was going to be making changes in the presser after the bowl game. Third, we saw some of the changes right after the bowl game (run game coordinator, CJ named starter, Seniors presenting "The Slight Edge", Staff visiting other programs during the off season etc.). Finally, many of the changes are not things you implement in a matter of a month or two between when season tickets went on sale, spring camp and fall camp.
People rationalized not buying season tickets because they wanted to send a message. If they want to believe their "message" was received in time to set the stage for this years success, more power to 'em. It makes for a good laugh.
