You have no idea what is on his immediate agenda and what is not. Nor does anyone else here know either. Or if he even has an "immediate agenda".
Most experienced managers take time to assess their new environment and responsibilities before taking any major actions, such as firing another high level person.
I think that it's extremely unlikely CCC will be replaced for the upcoming season. Nor should he be.
The original poster raised a completely valid pair of questions.
1. Does anybody know anything about the new AD? (I do not)
2. Does anybody have an opinion as to how the new AD will view/treat Chris Collins?
He correctly points out that a replacement AD from outside NU is "different" than promoting someone who already has a relationship with Chris Collins, implying it may be negative for the coach. In my opinion, that assessment is reasonable and probably true.
Then he points out or reminds us that the new AD has to find a baseball coach ASAP.
You respond with "You have no idea what is on his immediate agenda and what is not. "
Of course, he never claimed anything like that. Nor did he say anything about Collins being fired immediately.
So my question to you is... What is the opposite of helpful?
