I'm pretty sure it's not true. There was an article in which another player or maybe a coach commented on Little by saying "you know you are good when you are good enough to commit to Notre Dame".
It didn't mean he actually committed to Notre Dame, just that he has the option to do so. I saw someone post this in a thread on BGI and for whatever reason, everyone who replied misread it.
Hopefully I'm wrong, though, I'd love to get a 9th.
