Nor does it excuse this:
Also not excusable? That Harrison wasn't even penalized for either of those hits. In both cases, it was blatant, vicious contact to the head of an opposing player, and to miss it both times is astonishing.
It's time to decide, NFL: You're either serious about the concussion issue or you're not. If you are, something needs to happen to Harrison here. A substantial fine, at the very least. A suspension is preferable. And the officials shouldn't go without some kind of reprimand, either.
And I know that some of you are thinking, "It's football! Hits like that are part of the game!" My response to that is yes, you're right, hits like that are a part of the game, but that is precisely the problem.
Hits like that need to be eliminated from the game. Hits like that are the reason that careers end early and NFL players spend their retirement years drooling on themselves and confusing mailboxes for their grandchildren.
Here you go, Commissioner Goodell. If you mean what you say about taking concussions and blows to the head seriously, then show me. Do not let this slide.
