Of the millions of concussions athletes get, how many of them randomly pass away from them a couple months later? It just doesnt happen.
They are still doing extensive research to understand the true nature of contact sports related brain trauma. No one knows all the answers. I realize it is uncommon, but that doesn't make it impossible.
However, not to turn this in to a debate before we even know how it happened.
Any of the reasons he could've died are horrible. Concussion was the first thing that I thought. Out of left field, but also a viable thought when a young athlete just dies, but I hope he wasn't ****ing with PEDs or anything like that.
I'd be hugely surprised if it turns out to be directly related to his concussion (my best guess would be heart problems for some reason or another) but no matter what the cause, it's pretty messed up and sad.
From all accounts he was a great person and good guy to be around and losing those people is a sad thing
