From what I understand on the pipelines...
1. If Teambuilder, you get what the team you replicate has (i.e. if you have Alabama as a model and then assigned new names, you get Alabama's pipelines...etc...
2. With in-game teams, it is based on their initial hometowns. Check your roster for home towns and adjust to get NY/NJ like it should be. I thought it was 4+ from each state but maybe that is just being safe.
3. If that does not work, I got nothing...
