I think the underlying problem there is that PIT appearances save Big 6 teams' jobs. If a person gets there every season I can live with that. When a guy is able to ride along because he makes it every 4 seasons or so, it's a bad process
I'm not in Allen so I don't know of the issues there. Your resume should get you whatever low prestige BCS jobs are out there. Everyone goes through the process of taking a non-BCS school to success, in order get a BCS job. There's a very rare occurrence of a highly successful DII coach getting a low BCS job. So I don't think people qualifying is an issue.
As far as qualifying for the PIT, there's ideas out there to make it so you must finish .500 or above to qualify. I've been against that, but when I see a 9 win team make it in, I don't like it. I do like the idea of if you when your regular season conference championship you automatically qualify for the PIT if you don't win the CT. For clarification that would only be 1 team per conference winning their conference championship. So if two schools finished conference play 12-4 in opposite divisions (North/South, East/West), whoever won the H2H between them gets the bid.
I looked at 1 world (small sample size alert) a while back to see the effect it would have, and it would result in 3 different teams making the PIT, and knocking out two BCS schools and 1 midmajor school. Non of those were sub .500 schools.
