He may not want a better gig. He will probably get the greg Marshall treatment and thrown a huge amount of money to stay their and coach
Seriously doubt Loyola will give money to a coach at that level. That kind of school just doesn't throw money at sports the way a school like Wichita State does.
This is Moser's 3rd head coaching gig. Looking at his career, he seemed to be on the fast-track early, getting a HC job at 32, spending 3 decent seasons at Arkansas Little-Rock, then jumping to Illinois State by choice. Then he stalled out- 4 years at Illinois State, fired, back to being an assistant for 4 years.
So he can look at it 2 ways. That this is potentially a big payday (almost certainly somewhere besides Loyola), or be happy with the job security he's given himself, and stay right where he is.
