Kiffin isn't an idiot. He just doesn't have the same set of ethics I do. He knows how important it is to be the first school to offer a recruit, the first one to "notice." For the next while now, that boy is going to think of himself as a USC quarterback, and when and if it comes down to choosing between USC and another school in four or five years, I'll bet USC has the edge.
I wouldn't offer him, though. It's important for this kid's education off the football field that he thinks for another couple of years that he actually has to work academically to get into college.
