Jason Kelce has talked about the play being gruelling on a Centers body, but he does not think it leads to more injuries, for whatever that is worth.
I am a mixed bag. I dont like the play. I dont like the current rationale for removing it. I do like my coach being willing to vote according to his loyalty to the game, and not the team, first. At least thats my view of it
(Im also confident McD doesnt do this without talking to Beane, Pegula, Josh, and McGovern)
