It's potentially upside if you suppose that more will join us than leave us. Sure, we will grab a bunch of highly 'rated' recruits that weren't good enough or tough enough to hack it at schools that we would like to beat. Is that what we want? Tech can be a tough place academically at times, many will come to Ma Tech and tend to think the grass is greener on the other side. Saban has a point; the weak will turn and run from the adversity, and I agree that is not best for developing young men and women. Better to fight and develop character.
I also hate the potential that athletes on your campus may still be approached by bagmen to flip. You still have to recruit the guys who are already hitting the field for you!
