I am playing in this online dynasty league called Gridiron Dynasty. It's got all D1A, D1AA, D2, and D3 schools, and the idea is to have each school coached by a human player, who does all the gameplanning, recruiting, etc. I am new to it and just took over a school in DIII (Bridgewater State), but it looks fun. It's about $10 a season (5 weeks, ish), but if you look hard enough (like on google), you can find a promotional code for a free season... and by look hard enough I mean it's obvious to find.
The signups for my league are open, and my tag is goodoldalky. If you think it may be your thing it's pretty much a win/win since you can use the promo code to try it out for free.
You can look at the basics of the game here:

I did a google search and got the free season at a link that looked something like the one below:
