I think there is a certain chain of command in the whole topic, and probably why I get a little bent here and there with certain players holding others accountable.
IMO, the coach and his staff should be the ones handing out the Coughlin type reactions and discipline, not a fellow teammate trying to do it.
But I have little problem having a coach walk out onto the field and chew someones ass when he fails, especially at the NFL level. In this case, the punter had specific instructions and he failed to deliver upon them and little other than his execution was to blame.
You have to get through to them and hold them accountable, doing so on a big stage as a game should get through. If it doesn't, well then either they can perform it as written or they can't be counted on in the heat of the game.
Either way, they probably don't fit upon your team for long term success, in this case, this isn't the first mistake Dodge has made this season.
Personally, this is what I would like to see Campen or Mike McCarthy do to say a inconsistent yet talented player that loses focus at times.. Colledge comes to mind almost instantly.
And it has worked.. in 07' when Colledge was struggling, he got called out and benched.. he returned to play some of his best ball of his career. Last week Campen comes out with a strong statement that everyone on the line failed.. they returned with one of the most complete performances of the season.
Why do it.. because it works in this setting. Not all setting, but sports, especially on this level, you do it because it gets results.
