I'll summarise your original post more sharply to help you write more succinctly. You didn't need to waffle on for paragraphs in your online journal, you could have responded at all but you didn't.
Next time try:
"Decisions take time, I have full trust in the board. They definitely have someone already named behind the scenes, someone REALLY big but disclosing it could be bad to the new coach! There are no bad optics here at all"
Now read that shortened and look how dumb it sounds to defend that position. Fans, sponsors and performance wise to do at the start of a season is dumb. You don't need to waffle to pretend to be right.
