I was very critical of John Kelling during his tenure as co-Defensive Coordinator. The reason was because I saw his secondary regress every year he was at the helm, while Mannassau's front 7 typically played quality defense, and at times even stellar defense as far as stopping the run.
Much to my delight, Kelling departed during the last off-season and the entire defense was handed over to Mannassau, a change that I trumpeted. As we all saw, the 2012 pass defense continued to be pourous, while the normally stoudt run defense was even worse.
My point is, a simple coaching staff change, whether it be the head job or assistant positions, does not automatically translate to success.
My personal opinion is that both Mussman and Mannassau have built up enough equity within this program to be given more time to prove themselves. Circumstances like the transition and the nickname have been discussed ad nauseum, so I won't revisit those issues again here.
Regardless of any circumstances, it is not like the last 5 years have been a disaster, although they certainly could have been better. There have been some embarrassing losses like Sioux Falls and blowout losses like EWU and MSU. There have also been quality wins against Top 25 programs like Cal Poly in '09, and USD and SUU in '11, a finish in the Top 25 polls, and a conference championship.
Has it been all roses? No.
I may change my tune if we muddle through the next 2 or 3 seasons near .500, but for now I would like to see what Mussman can do with this program in the near term with a level playing field and solid footing in a quality football conference.
