This search has gone on for a while. Many of us should step back and go with the most logical answer. Who is a grinder? Who is a developer? Also said person(s) could still be coaching in CCG's. This could be anyone, so I won't even bother throwing out a name just for the sake of it.
All other names are being thrown around for one reason -- money. Everyone's looking to get that raise and get paid. It's nothing new in the wide world of sports. We can sell our fan base to a prospective coach, our facilities, at the end of the day it's going to take the right Jimmies and Joe's to turn this program around.
Find an identity, recruit to it, stick to it. We are in a much deeper rebuild now than when SF was hired, IMO. We're at a distinct disadvantage with recruiting. We will never out recruit Ohio State, Michigan, or Penn State. We need to recruit to our system, our schemes, what our identity is going to be instead of just being an after thought for recruits. Because of recruiting, this is one reason I think a higher tiered "outsider" coach won't come here unless we pay big-time money (which we won't) all candidates will be flattered and thank us for getting them a pay raise but that's about it.
It's a hard pill to swallow but this is the reality. We need a Bret Bielema kind of coach that can turn things around fast, develop this roster quickly in year 2. We were great in the past because we made our identity to be that we would out work our opponents and would be the most physical team. Time to get back to building OL, DL. This hire is crucial and important for this program to have any kind of future success.
Remember, this is Trev's decision and his hire will ultimately judge his tenure here. It needs to be a good one, or this fan base will be lost completely.
