Agree with your question and observation. If it were me and I was on #5, 6, or 7 - that would give me pause. The evidence is already out there that things are only going to get worse not better if yet another concussion occurs. Perhaps Sean is aware of this and the discussion has already been had - who knows? Really, it isn't our business. Last thing I would want to read is some evil story of some evil crap that happened due to some CTE garbage. I would rather see him walk away and enjoy what little time he has left on this rock before crazy time sets in......I mean how many hits before he looks like Dobler does now? If you haven't see a recent picture of him I suggest you avoid looking cuz it ain't pretty.
