TL,DR: I feel like I am 100% in the minority here where I don't really care that Turd left. He has not helped his cause in any way by his actions or his words, but the decision to leave doesn't really have me feeling any negativity towards him. He has left the AD in a better place than he found it, which is more than we can say about pretty much 4 of the last 5 ADs (TO at least left it the same if not better). Nebraska will be a pretty attractive job for many candidates because of the current state of the AD and the money we are willing to spend.
It is easy to see that the AD is in a better place since when he took over, which is really all we can ask of whoever the AD is at Nebraska. Turd threaded the needle with Frost to appease certain people before letting Frost hang himself, and then brought in a well respected coach who we all seem to be excited about. He threaded the same needle with Hoiberg, and that situation allowed Fred to grow and turn his program around. Baseball is trending up, volleyball is still great, women's basketball is doing well, softball has one of the top talents on their roster, and other sports are also seemingly doing well. He launched the ambitious plan of renovating Memorial, which is long overdue, and he has listened to the fans by adding seating to Bowlin Stadium, working towards adding beer sales, and generally uniting the AD (Rhule deserves more credit than Turd here, but the point still stands).
When Turd first took over, the AD was a complete disaster outside of basically the volleyball program. Some others were showing life, but the main money makers, football and men's basketball, were complete shit. That doesn't seem to be the case today.
As far as him taking a seemingly lateral move for the same money and a smaller contract, that seems to show he was really not happy with different things going on behind the scenes (again his previous words about being so happy here, yada yada yada, do not help him in any way). Whether those issues are political, lack of University President, disagreement with the potential University President, the lawsuit, funding issues, whatever, it obviously seemed to be a major deal breaker in him staying here and his potential ambitions for the rest of his career.
The political issues seem to be the reason gaining the most steam as the reason he is leaving, and it is something that is a major issue in this state. The top leaders in this state are obviously right-leaning, and while that is good for this state in many ways, it definitely seems to have negative consequences towards the University. Decreasing funding for the school created issues that seemed to at least contribute to the previous Chancellor and President leaving. It also seems like that may have some consequences on getting new highly qualified candidates as replacements. While not directly related to the AD, it does have other consequences. Turd was also fighting for private funding for the stadium, as well as trying to get fans to help fund NIL. Getting that funding, while the University is also looking for funding, seems to has caused some type of issues. Whether that be donors not wanting to help in this current climate or determining where the best place to place their donations (stadium vs. NIL vs. something else), it appears to be causing some turmoil within the entire University.
Compare all this to TAMU, and they don't seem to be having the same issues. UNL is currently trimming their budget by $12 million. On the other hand, last year, TAMU received a record (for them) $1.19 billion for their budget, including raises for some of their employees for the next 2 years. They also have completed their stadium renovation, and their football coach is new so Turd wouldn't have to worry about that in the immediate future. If Turd's ultimate goal is to continue moving up towards conference commissioner of CFP chairman, moving to A&M is a smart move, even if it is currently a lateral move as an AD and it feels traitorous as a Nebraska alum.
