Technically he's not cleared to play yet. Probably will get clearance from the sound of things, but we'll see.
No doubt that much of the "hang-'em-up" talk comes from people who just want him gone, but also some seem to have an overblown sense of the risks. Like they think he's one good hit away from being a vegetable.
I will admit I feel this way about him. I don't know why. I know it's pretty negative but I'm always worried when he gets hit awkwardly. I feel the same way about Zetterberg. The Jamie Benn hit I literally threw my glass watching it live.
