You're confusing what a blue blood means to a coach vs. what it means to a player. Guys like Cal and Pitino cared about the status of Kentucky. That doesn't mean players did or do. In the '90s and before, sure, a blue blood program had a huge draw. But once the one and done train got rolling players didn't care.
The proof is simple. If Cal did not come to Kentucky where do you honestly think Wall and Cousins would have played? What about Brandon Knight? Anthony Davis, MKG, and Teague? If the answer is anywhere but "wherever Cal was coaching" you're 100% mistaken.
This board has spent the last 15 years complaining about how they were sick of players coming here for Cal and his one and done system and now you're all trying to convince yourself they came here to play for Kentucky instead of Cal. Kentucky may have helped land some of the fringe one and dones, but 95% of them came here for Cal.
