From what I've seen here and some talk I've heard, the list is:
1) When he signed on, Schloss was promised some facilities improvements, not just to the ballpark, but also practice facilities and such. Those were slow played after the Jimbo firing.
2) After their success in 2023, Schloss asked for more money for his assistant coaches. He was turned down, because Jimbo.
3) As part of the post Jimbo austerity program, some of the baseball support staff were let go without letting Schloss know until after it was done. When he protested, he was told that it was just that way and he'd better get used to it.
4) Alberts heard that Schloss was dissatisfied with the above developments and might consider looking elsewhere, so he called Schloss into his office and basically told him that if he was unhappy at A&M, he should look elsewhere. He invited Schloss to leave.
In short, A&M Aggied it up as only they can. Why would anyone want to stay and be part of that kind of unprofessional cluster fuck?
