I'm going to take a unpopular position probably here. As per Saban "processing" players, he is in a unique position where he can get away with it. It's called WIN AT ALL COSTS. And the reality is there is no NCAA rule against to my knowledge.
The key here is it seems to be working. You can only have so many scholarships. And if 2012 Recruit A is better than 2010 Player B, then by processing him your team is better. And it seems to be working fine for NS.
Processing stinks, and its happening more than ever as it becomes accepted as a cost of winning. The thing is, the time spent talking to recruits' parents virtually ceases once the LOI is in. So NS doesn't have to explain anything to them.
Processing is just another rotten part of the recruiting game, and things aren't getting better. The honestly with existing players is going downhill, and so have recruit's with colleges (see GK). It's one big lie-fest sometimes.
Recruits would be wise to not spew off on their choices, when beforelong the recruit may be processed before they sign their LOI. That's called "cooling".
As long as a recruit gets good advice, they should know what they are getting into, anywhere, but especially Bama. They do it because they want to win. A-list players maybe won't have to worry, but anyone else should. It may be bush, but it's not illegal. And it's working.
