@jaybate-1.0 Football and basketball recruiting are two very different animals. In college football, you have 9 assistant coaches on staff that are on field and allowed to travel to recruit. KU, or any other program for that matter have only 2 guys focused on recruiting. It's more like 7 guys focused on recruiting out on the road during the week. The HC, OC, and DC do not spend nearly as much time on the road during the season because of their game planning responsibilities. The film study now is pretty advanced because there is a company out there that will actually break down game film at the NFL, college, and even HS level by play types, what they run on specific down and distances, time left, etc. This is a paid service so not everyone uses it, but it really cuts down on the amount of time spent analyzing film because everything is already categorized. That said, it is the still the those 3 who come up with the overall game plan each week.
Beaty did hire a lot of other really good recruiters as his position coaches which is why KU's recruiting has picked up the past couple of seasons from Weis. Turner Gill also had a lot of really good recruiters on his staff which is why his one full class was a highly ranked class by KU standards. David Beaty's primary job now as a recruiter is to talk to recruits over the phone, either actual calls or texts, and to close the deal when his assistants get kids to campus for official and unofficial visits.
The Jim Tressel analogy does work because of the question of you asked. You asked could an NDSU level coach, Youngstown St. was at the top of the FCS food chain under Tressel, recruit B12 level talent right out of the gate if they were hired by a B12 school. Tressel and OSU are B10 obviously, but for a program like OSU to hire someone from the FCS ranks, that was a huge risk for the program because we've seen what can happen to historically dominant programs when they are down, and hire a new coach. Nebraska has never fully recovered from Bill Callahan, Miami hasn't recovered from Randy Shannon, ND was way down for a long time, Michigan is only now recovering from Rich Rodriguez, Texas is struggling big time under Charlie Strong, Florida tanked under Muschamp. Those weren't even FCS to FBS hires, but those were still bad hires that set historically great programs back significantly and some still have yet to recover.
KU failed at following up Glenn Mason with Terry Allen from the FCS ranks so it is absolutely a risk, no matter where level the football program is at, to hire an FCS coach straight to the FBS level.
