I'm disappointed as a fan that Burns is leaving. But as a fan, my loss is only in the entertainment department. I'm not losing money or a friendship or a home.
Let me frame this situation another way, speaking generally---not about Burns specifically, as I don't know his personal goals, motivations, thought process, etc.
Let's say you have (or your son has) a talent, a desire, and you keep developing them until you have a real skill that will soon be potentially highly marketable.
So now you have stewardship responsibilities for that skill. If you're a wise steward, you protect your health with proper exercise, nutrition, sleep, etc. You also practice, and seek the best available instruction, coaching, and mentoring.
If your skill is very specific, like pitching or golf or shooting, and the rules offer you the option to study/play under more than one excellent coach... do you take that option? Do you seize that opportunity---not out of dis-loyalty, but as a logical, responsible stewardship of that gift?
Like I said, this is just one of many ways to frame the issue, and it's certainly not one that I can condemn.

Now I ignored NIL* in this presentation of "stewardship." But anyone can see that the risk of career-ending injury has a bearing on stewardship of one's future. Most college students leave school with a degree and debt, and not many careers afford an income that makes paying off debt quick or easy.
So even if you leave college with your athletic dreams shattered--but with a degree and some seed money to start your life in a new direction--yeah. That's good stewardship, too.

*As I've said before, I believe NIL was foisted on the NCAA not to improve college athletics, but to destroy it.
