If Brohm losses only 6 games in his first 4 seasons then you can begin comparing him to Urban Meyer. Currently he is 3-2
like i siap, i think it's harder today to identify the urban meyers of the world because of the attrition that takes place at head coach positions across the country.
if you look around at all the major programs that have made changes in the last 5 years, not everyone is hiring a top coach. most are getting 'up and comers'...some maybe before they've reached a level some think should qualify them for the type of job they're taking. here's some programs that have made changes over the last 5 years...

and those are the ones just off the top of my head. and what's more, aside from a few obvious ones on this list, a lot of these schools hired 'up and comers' or coordinators from p5 schools....and as that has happened, those 2nd tier p5 and mid majors have had to replace as well....meaning that the pool of coaches at that level right now, most all are relatively early in their tenures....so the resumes are "short".
point being, the 'pool' of coaches to select from simply isn't as deep as it was 10 years ago, when there was more stability at the top of these p5 conferences.
also, some of these schools have made more than 1 change in that time frame. further depleting the pool.
so imo, it's simply just not as easy at was 10 years or so ago to identify an 'urban meyer'. and you have some coaches, like a Gary Patterson or Chris Peterson, that most any program would hire, have simply decided to stay out of the rat race and stay put.
edit: which is why a guy like Brohm does sort of stand out...he's made the right progression of steps that you saw with a guy like Meyer....mid major (WKU/BGSU) to 2nd tier P5 (Utah/Purdue). it also doesn't mean that there aren't good coaches that can run this program the way we expect it to be run either. it's just not going to be as obvious as many want it to be.
