Very sad to say the least... way too young.
"Police told ESPN that Jake's death was not considered suspicious"
I'm going to make a possibly ignorant sweeping statement, but...
20 year olds, especially athletes, typically don't die of natural causes.
I'm not saying he didn't, but statistically, it doesn't add up.
But... the Dad died young too (46) of a heart attack.
It could be something congenital/hereditary.
Either way... very sad day (again) for that family.
