Indeed, there are way too many factors in play to just let some guy onto the pitch while there's a serious medical emergency. He was already getting professional attention, I doubt one person more would've changed anything.
A Detroit Red Wings player had something similar happen a few years ago now during a game and he was forced to retire, obviously a different situation, so who knows. That's the least of it at the moment.

Fair enough, obviously we have our share too. Just usually don't see them at sporting events. I can probably count on one hand how many time's they've gone to a crowd shot and found someone attractive.
