These is what I do, I'm ISU and this seems to be a pretty good fit. I'm 5 years in and my DL and OL are the strength of my team.I have it unlocked but I haven't spent points on it yet. The recruiter tree is probably the most useful, but think the tactician tree is sneaky good as well, especially with a small school, because it literally makes players better. If you get to level 4 for any position group, it can add 3-4 points of overall rating to players. It's really good for the O-line and d-line.
I currently run both tactician and recruiter, and it feels pretty solid
I've read online that going recruiter hurts you for getting job offers but I'm not interested in leaving for awhile so I haven't paid much attention so idk it its true.
