Don't listen to Dahs, wildcat. The jobs process does not, and isn't intended to, mirror reality (otherwise we'd all have to spend 5-7 seasons as a D1 assistant coach). It also doesn't matter whether your wins are against humans or sims.
The thing that does matter is post season berths and wins. The big problem for low D1 teams is making your schedule difficult enough to make an at-large bid possible, without risking losing too many games before the conference schedule even starts. You simply cannot schedule bad teams, even bad Big 6 teams hurt. You also cannot schedule many great teams or you'll just help them by losing.
One big problem with taking a low D1 rebuild is that the jobs process looks at a 10 year history and penalizes those that have a few bad seasons at the beginning. Even when your loyalty is back at A+, you have to consistently make the NT to be able to get out of that job. If you don't, then you're lucky to be able to move up to a higher baseline non-big 6 school.
I'm not sure why you wouldn't get accepted at a "keep looking" job. I think that indicates a lateral move that will hurt your loyalty rating. If the school has better players, higher baseline prestige or is better situated to succeed, then it may be worth moving anyhow.
