Absolutely. As I mentioned above, if he's 100% certain ND isn't for him, he can play in South Bend as a freshman, transfer immediately after the 2013 season, have his "redshirt" year run concurrently with his 1-year transfer penalty, and then still have 3 years to play at his school of choice. All that, and he gets a 1-year scholarship at an elite academic institution.
If he chooses to break his LOI, he can either: (1) sit at home for a year; (2) pay his own way to UCLA (but not play as a freshman); or (3) go to a JC. And then he'd still lose a year of eligibility on top of that.
Showing up at ND this June is definitely his best play.
