The world of college football recruiting has completely shifted in recent years. Transferring has become commonplace, and after years of confusion over waivers and needing to sit out a year, the NCAA finally changed the rules to allow players to transfer relatively freely.
Some coaches have been critical of this, as they claim this essentially means college football has free agency now. Of course, this is really more complaining that their job changed, and got harder in the process...Yes, you need to make sure your current players are happy in the program. Coaches also need to find the right balance between taking in transfer players and taking in freshmen too.
