I respectfully disagree with these assessments. If you want to play D1, there’s no reason not to try to get there ASAP. I’ll make a pitch for the D2 conferences I’m in, but generally D1 is the draw and I get that. It is quite a bit more fun in the right situation (good conferences) too. So I understand wanting to get there fast.
In my view, the reason to invest and settle in to a fun D2 conference before moving on to D1 is not really about not getting slaughtered when you get to D1. Under my original handle in my first world, I moved to D2 after my first season, made a handful of NTs, and went straight to a mid-major. I was never “slaughtered”. I was observant, asked questioned, figured stuff out. Didn’t worry about championships. Had some fun. But then again, my first power conference job was Rutgers, so take from that what you will. If you understand how the game mechanics work, there’s no reason you can’t build a team that can compete for a conference title most years almost right away, if that’s what you’re looking for. Though I will share this. I, too, intended to use my stop in the N Central as a quick layover to a fast mid-major route in Knight. I stayed because I liked the conference and I started to like the experimenting I was doing with this particular team, but also because the longer you stay in D2, the better your D1 choices get when you jump. Now I’m at the point where I’m being very selective; if I do move up, it has to be the right team. Either my “dream job” has opened up, or a high baseline prestige job is available, and I’m qualified for it.
So it becomes an issue of A) whether you have the desire to undertake a real rebuild, and under what circumstances; and B) if you really want to deal with the extra problems of D1. As a new coach, if that’s what you are, you should understand that while the game mechanics are mostly the same, D1 has some new problems. The top teams you’ll have to beat to advance have baseline prestige advantages over you, meaning you start recruiting with a deficit against them. And when you do score elite talent, it’s volatile. You have to manage early entries to the NBA. Some coaches don’t like dealing with those problems, and find the straightforward nature of the lower levels more gratifying. Making sure you know what you want out of the game is probably the best reason to take your time, IMO.
