So I see two different questions in this thread - the first is whether a few teams dominate winning NCs in DII and the second is how long it takes to build a "rebuild". The first I don't have the bona fides to adequately answer, but for the second one I do. I took over Western New Mexico in Rockne when they were absolute dogshit ten seasons ago. I left last season where they finished in the top 10 and won back to back conference titles. It was my first time ever in DII.
For recruiting, Western New Mexico doesn't have a great 360, but you have access to California (closer to LA than Humboldt) and you're close enough to Texas to get a few recruits there. You have enough room on the West Coast to get the recruits you need without facing a lot competition. It's tough to recruit SimAI players, but easy to get Undecideds.
Formation wise, it's best to keep it simple. The WNMU team in Stagg right now is practicing 11 formations at the same time, not including special teams. That's absurd. I would practice no more than 4 plus special teams and dump the rest of the minutes in position practice. The Rockne team I had at Western New Mexico used one offense and two defenses. As a result, I could tailor recruiting and game planning strategy to my formations.
Game planning takes the longest to learn and separates the good coaches from the elite coaches. For now, the best advice I have here is to abuse your best players. It's not worth having a D2 QB run instead of using your RB1, even if your QB is the second coming of Michael Vick. On defense, I have never had a lot of success with blitzing compared to when I dropped everyone back into coverage. Check your own game logs for more patterns. Yatzr's tool is good for that.
As for how long it takes? I found 4-5 months at the minimum builds a consistent playoff team and 8-10 seasons is more than enough time to build an NC caliber team with the right coach. YMMV.
I truly think with the right strategy that is possible to win an NC at DII at almost any school. South Dakota is in the finals tonight for Wilkinson's NC - it doesn't have a great recruiting base, but it has had human coaches for 40+ seasons to build a good vision and create a good program. It takes a combination of skill, patience, and luck to be good at this game. Patience is most important, followed by skill, followed by luck.
Also feel free to PM me if you have any questions on Western New Mexico.
