You do know that previous concussions are a strong indicator and risk factor for future concussions, right? Hasn't Skinner had like 4 major concussions that kept him out of games?
He's had 3 total. Although it's hard for me to say what is major and what isn't, I'll go by games missed. He has not had anything near to what Crosby had, not even close.
Skinner's 1st concussion, I'd deem as major. He was out for 16 games I think.
Skinner's 2nd concussion he missed 6 games.
Skinner's 3rd concussion caused him to miss I think 3 games.
I agree that concussions are nothing to brush off lightly, but the constant comments that "he's 1 hit away from drinking his meals through a straw" is a bit over the top and what fans are reacting to. Nobody says it about Crosby or other players who have had either multiple concussions and/or much more severe ones than Skinner has had.
Is he at risk? yes. Is he at an elevated risk due to history? Yes. Is he 1 hit away from retirement? probably not much more-so than other players as anyone who takes a devastating hit to the head can be done.
EDIT: where he could be more at risk for leaving the game is if he decides the CTE risk isn't worth it any more and hangs them up. To me, that's the biggest risk if he has another
