You don't need "real insight" to know the dangers of concussions. And Olave has had FIVE of them.
There are plenty of peer reviewed studies that detail the lifelong and irreversible damage concussions give to the brain. Just like how it doesn't take a doctor to know smoking cigarettes is horrible for your health.
I said what I said. We don't know the severity of his concussions. Have you reviewed his scans? Spoken with the independent neurologist who cleared him? Ok then.
Most of us who played have had five or more, even if we didn't know it. It's part of the game, and we signed up for it. Paid for a good chunk of my college tuition, and it's paying Olave a LOT more than that. Life is littered with risk, personally and professionally. If he decides the reward is worth the risk, he'll take the field and you'll be cheering your arse off. We get it dude, your heart bleeds for Olave. He'll do whatever he does.
