It's unpopular for many reasons, but at it's core it helps the factories get rid of their recruiting mistakes and hurts programs like GT who invest a lot of money, time, and effort to recruit guys like Singleton and Rutherford only to have a deep pocketed factory buy em, once they see that we found one they didn't.
The only help to middle programs like us, is it helps with depth. Are there exceptions, of course there is, but this crap is out of control and much much worse than the bagmen of the past.
Another unpopular facet of cFB, is the constant roster churn and little to no true affiliation for the school that first signed you. A LOT of these kids would have never developed to the degree they have if they first signed with a factory. Do they appreciate such, obviously not.
