Goodnews. Excellent point that is hard to disagree with. But let's look at this from another perspective. Wolford had many veteran coaches and constantly bragged about them. Yet those he brought in on the defensive side of the ball failed, and failed badly.
On the other hand, Tressel had Conatser (spelling?) and veteran and respected high school coach Bob Stoops. Usually, the rest of this staff consisted of young coaches trying to make their mark in the profession: Dantonio, Bollman, Treadwell, Heacock, the much maligned Klacek, and even student volunteer Mangino. All of these men advanced to be head coaches at the college level or coordinators at big time programs. All of them had the same standing as the "kids" that Pelini uses when they worked at YSU.
So given the financial restrictions of FCS football, is it better to hire inexperienced, ambitious young assistants or established, experienced veterans looking for jobs? Or perhaps a mixture of both.
