I have been tring to find this out for 2 days now.
it does not seem like any one knows for sure.
i have read that it is 3, 4, or 5 players.
Some say that you have to get all of the players in one recruiting class and some say it does not matter as long as their are on the team.
I also heard that you can lose pipelines.
Below is the best response i have seen that makes the most sense, but again they are not for sure.
I wish we could get a good answer to
how many? can you lose a pipeline? are there levels in the pipeline? (ie if you have 10 players from one state and you are recruiting from that state, will you pipeline bonus be larger?)
