You are joking right? It is true that occasionally a FCS team (1AA) steps up and beats a BCS level (1A) team and other times the FCS team puts a scare into the BCS team but the jobs are entirely different. There are some schools at the bottom of BCS like the Sun Belt teams or the bottom end of the MAC that are not far above top teams in the FCS like Montana State, Appy State, etc. Those aren't what we are talking about here.
Most FCS teams have a total football budget that would be a drop in the bucket compared to most schools in the AQ conferences. UNC isn't recruiting against schools that fly coaches in with helicopters to impress recruits and use private jets to maximize recruiting efficiency when their coaches are on the road. Most FCS recruits aren't even on the radar of the BCS level schools. FCS coaches normally make less than position coaches at the bigger schools, staff sizes are smaller and support staffs are way smaller. A big difference is in the nature of the job itself. BCS level coaches are responsible for feeding those bigger budgets with significantly higher levels of fundraising and public relations. Coaches at FCS schools have some of these responsibilities as well but on a hugely lower level. They are not the public face of the university, they are not normally the subject of daily newspaper coverage, attention from the nightly newscast, or from the internet geeks like those who hang out here.
Logan at Mullen gets more media attention and frequently larger crowds at games than he would have at UNC. At UNC he would have to give up most of his media work and a lot of his endorsement work. In exchange he would be getting a program that needs to be rebuilt from essentially the ground up. UNC doesn't even have the budget to fully fund their allotment of schollies. Recruiting trips are limited by budget and being a long way from Texas and Cali is difficult, as a result most recuits come from Colorado and surrounding states out of neccessity.
I think had Logan decided a number of years back to aim at a BCS level head coaching job he could have had one by now. To do so would have involved making some sacrifices and being either a position coach at the BCS level or a head coach at the FCS level for a time period first. At this current age that time has passed. Had he taken the UNC job it would have been a terminal job for him. Saying he spent three years there he would be 60, past the age when any quality BCS school is going to offer a job to someone with no prior BCS level head coaching experience. Without that intermediate experience he has and should have no chance. The past history of HS coaches going to BCS level schools is not a good one with guys failing even in situations where the program was already set up to succeed. It is a whole different world.
The media guys in Denver will continue to put Logans name up for every coaching vacancy that comes up because they like him, they like to think that they know enough about sports that they could coach and if one media guy makes it that validates them, and mostly because they are lazy and plugging his name in saves them having to actually research who is a legitimate candidate.
