Dustin Fox has the right view on this.
That some bowls are "meaningless?" That's one of the things he said.
They are.
If you're Leonard Fournette, who is probably a Top 10 Draft Pick even with his injury issues, what's the point in playing Louisville in the Citrus Bowl when any of the following could possibly happen?
-career-ending injury which leads to not getting drafted
-career-changing injury which leads to depleted draft stock
-more wear and tear on a body that's already been put through the ringer in one of the hardest hitting conferences in college football
-more wear and tear on the brain, because concussions and head trauma actually do cause problems later on in life
Playing in the Citrus Bowl holds virtually no value to him. He's shown what he can do at the college level against top competition. What more would a good to great performance in this game prove what we already know? He's making the smart financial and health conscious decision.
Had this game had some actual meaning to it (Playoff, NY6) I could see the reason for staying and playing, but not for this game. But the Citrus Bowl essentially is meaningless for a guy like him.
