The only problem for him where he is at is you need to have a pretty damn near perfect season in that conference to get an at large bid. They had two this year but how often will that happen? If they do lose some games throughout the regular season you're needing to win the conference tournament every single year. All it takes is one bad game or one hot team and you're not dancing.
A few years in a row of that and people can forget quick about little Loyola, especially if there is another coach doing something similar at another smaller school.
Do I think that could limit him? Probably not, I think he could still land a big job 5 years from now if they go 0-5 on NCAA appearances during that stretch, but you never know.
So, I'm going to indirectly answer this question, in two parts:
1. Here's the Big 10 coaches who were hired from mid-major programs that were subsequently fired in the years since Monson was hired at the "U" (1999): Monson, Richard Pitino, Todd Lickliter, John Groce, Ed DeChellis, Pat Chambers, Tommy Amaker, Archie Miller, Bruce Webber, Bill Carmody, Doc Sadler, Tim Miles
Here's the list either still coaching or left on their own volition (longer than five years): Fran McCaffery, Bill Self, Bo Ryan, Steve Alford (although he was under pretty heavy fire) (
should be noted that Steve Pikiell and Chris Holtmann should soon join this list)
I'd be prone to put Webber into the category of a successful hire for Illinois and Pat Chambers would still be at Penn State if not for the player abuse allegations, but all in all, it's a lot more coaches who don't successfully make that leap than those that do.
2. Since Dan Monson was hired by Long Beach State in 2007, they have had four seasons over .500 in his 14 years with one NCAA appearance. They have had five consecutive seasons where they've finished under .500, yet Monson was extended for five years in 2018. He's the winningest coach in LBSU history and at the time of the extension, he was the highest paid coach in the Big West conference.
Now, I'm not saying Monson is Moser's equal as a coach nor that Monson and Moser have similar aims in the profession; but as evidenced with Monson, you can carve out a pretty nice career at the D-1 mid-level without the pressures and demands inherent at a larger program.
