Chizik was fired, he was so bad. So, it's really not all about talent, is it.
The points are many. First, guys at Rivals, etc. use a method for determining talent that's not about an individual's skill or aptitude, it's about whose recruiting whom, thus Texas is always highly rated. Second, they can have all the talent in the world, but if the coach is Strong rather than Mack, they'll fail. And third, fans put way, way too much glow on recruiting rankings - like druggies, they're addicted to nonsense. It's why many now say, "I don't pay attention to recruiting."
