I agree. It's a mistake, and while ultimately understandable it's not the same as you or I breaking our hand after losing a video game, so let's not pretend that it is. Berry has a huge season ahead of him, and potentially millions of dollars if he plays well enough.
As an athlete his body is everything, so the decision calculus is way different than the average college student. It didn't cost me or anyone else anything if I broke my hand (minus a bit of pain and a small doctor's bill), as it didn't effect my studying or my minimum wage work at the campus store. A little different when you're the senior captain of the defending national champions at UNC.
