Everyone needs to get over it! Fred did not owe any of you anything, including Georges. He made a career decision that was best for him. As we all should do when making career decisions. He informed his employer once he had a job offer. That is the way life works. I am so sick of all the whining and Fred bashing. Be grateful and gracious and stop looking for a scapegoat every time something does not go your way. I'm not just referring to you but all of the Fred bashers and whiners. How long will it take everyone to just move on? I am sure some never will. I will just feel sorry for those people because they will never be happy.
Disclaimer: I'm not a "Fred basher." I'm not at all connected with the program and just read things as I live out of state. This is a Cardinal-tinted outsider's perspective. I don't have strong feelings regarding Fred one way or the other.
I understand your frustration with people being angry that Fred left, but I don't think there is anything you can do about that. Some people felt betrayed when he left, right or wrong. They justified in their own minds that betrayal with different reasons and when doubt is cast on those reasons the emotions resurface for them. You aren't going to change those peoples' minds with logic because they are responding to their own emotions; they just need time to get past it.
From my limited understanding of things, I think some of the things Fred did were good in the short term but probably were not great things for the program long term. I think accountability is one area he struggled with which has caused some issues for him his last year here and this year with the transition. While he was here, I saw a couple times that he "didn't coach motivation." Combining that while he was here with the statements of some of the Bulls' players this year that he needs to "coach players harder" leads me to believe he relied largely on players holding each other accountable for their effort.
In my outside but expert opinion, that can work if you have the right group of players (both leaders and followers) and things go well for the most part. However, all it would take is a few guys who aren't doing the right things who don't respond well to the leadership of the other players on the team for it to get messy quickly. There are situations when a coach should use a more structured/strict style of accountability when the players need it to get better. Just depends on the individual players and circumstances.
I would guess that might also be one of the reasons why Fred had trouble keeping a long bench of active (i.e., non-redshirt & sitting out) players. It would be difficult to motivate and keep younger players engaged with the team and motivated to give their all in practice to improve when they see older players getting play in front of them who aren't giving it their all in practice and aren't being held accountable. Currently, we have Georges and Monte who are fantastic but if their effort and leadership isn't fully supported and reinforced by the head coach it can be difficult for them to hold their peers accountable. Fred had a lot of players transfer out, just like McD, but Fred for the most part was able to balance that out his first few years by getting really talented freshmen (like Georges, Monte, and Matt) and supplement them with incoming junior/senior transfers. He wasn't able to do that well the last year (maybe two) because everyone knew he was preparing to leave.
We'll see if Prohm is any better at those things than Fred was these next few years. Having so many influential players graduating and so little current game-ready depth might be a blessing in that it will provide plenty of potential minutes next year for Prohm to sell to players current and future if they buy in to his coaching process.
