I'm taking a step back from most of my teams, but for me:
D3: Most D3 schools are no different from each other. Getting one (dream job) is also not difficult. As long as its not in some really bad recruiting area, I would pick teams based on their names or mascots. Candidates include - Misericordia, Hampton-Sidney (motto: Come here as boys, so you may leave as men), US Merchant Marines.
D2: St. Martins. I could have this job at any time, in about any world, but I've always thought about taking it since I work across the street from the school.
D1: I've always thought the best job in the game is UCLA.
