While I agree that the skit has gotten a bit lame and repetitive, I don't think it should be outright banned for all eternity due to this incident. If they do it occasionally, I am cool with that, but the guy playing Willie needs to be properly trained and not hit the guy running full bore like that. I don't recall Willie tackles in the past being that vicious. It does not have to be a full speed hit to get the point across to the crowd. That should be the lesson learned, and proper training and technique would fix that. But just to ban it forever seems a bit too kneejerk to me. If banning it would cause them to get more creative and have better skits, that would be one thing, but I would not hold my breath on that.
