Gotta be honest - I don't really care about recruiting rank bragging rights. If he'd committed today to Miami I would have been skeptical that he'd sign given that Bama wanted him badly. He already demonstrated he was flaky so the concern would be warranted. Wouldn't get too excited about a player that probably isn't signing.
I'm sure UF will do backflips and brag about rank when Collier signs even though we know he is bolting for LSU at the first opportunity.
It's like bank software glitching and showing you have one billion in your account. It's fun to take a screenshot and pretend you are a billionaire, but the reality is that money isn't staying there.
To put it another way, let's say you been wanting to smash some chick who is a 10. She keeps flirting with you and saying she wants to cook you breakfast in the morning. She calls saying she is coming over. Then a few min before she is supposed to get there she says, “Oh, I'm just a little tired lets take a raincheck.“ Then you go out to get a burger and see her car outside a club. A few days later she says she wants to come over. You going to say "nah, not interested" because you know she already lied once? Or just OK and wait and see if she shows up or not? Maybe hope for the best but get another booty call on speed dial who is a 9 that you know for sure wants to get down.
