At the time of the hire, I thought everyone was giddy and expectations were high. I don't recall anyone (at the time of the hire) say we're doomed and won't win more that 3 games in 2023 because he wasn't hired a week earlier. I think that feeling probably crept in after witnessing the exodus of a significant amount of talent to the portal *after* he was hired.
I'm not sure the timing has made a material difference anyway. Excluding the November hires and interim or internal promotions, all the first year coaches were announced within a two week period. It's hard to say that where a new coach fell within that two week period, by itself, had the most significant influence on his 2023 outcome. There are just too many other factors involved.
I suspect Mosely already knew he was going to fire Littrell if he didn't win the conference championship game (at least I hope he already knew) and had a short-list handy that he was already working. He may have even had preliminary discussions (if given permission) to assess the potential interest from his short-list. Anyway, we don't know when the initial offer was made or formally accepted. I'm sure there was some back-and-forth involved.
The announcement of firing Littrell was on 12/4. If Morris was always his guy, it could have happened on 12/5 or anytime before the 13th, if timing was going to be the ultimate deciding factor between improving on a 7-5 record or regressing to a losing record.
Here's the list again sorted on the date the hiring was officially announced.
