Saban doesn't care what Rivals or 247 think. That is the point. Just because everyone he recruits is highly rated by those services doesn't mean he cares what they think. Hell he probably has more staff members evaluating and rating high school talent than they do. If you are chasing star ratings in recruiting you are behind. I would posit that Saban knows about these kids before the rating services do and that is why he is consistently able to land them. If your entire stategery is to look at what star rating a kid has, you are already 2 years behind on recruiting him.
Saban does not pay attention to star ratings, but he damn well pays attention to other schools' offers.
