Ignoring the whole dirty/clean argument (which is pointless), if that type of play is implicitly or explicitly encouraged by the league, any team could come up with a middle blitz package and take out any QB in the league. At worst, they would risk a 15 yard penalty in the attempt. Ethics aside, that would seem to be worth it in order to face a Sorgi-led Colts team.
And once one team does it and profits as a result, you have the Chicago gangster rules. You knock our QB out of the game, we knock yours out for the season. Does anyone want to see that?
To be honest, I thought the league was pretty clear that they never wanted to see a player like Carson Palmer lost after getting crushed in the knee while exposed in the pocket. I'm not pushing for Pollard to be suspended/fined per se, just expecting the league to put out a strong statement about not going low after a QB in the pocket. Just seems like common sense to me. At least something good may come out of this suckish situation.
If the league puts out a statement that the play was totally legal and says nothing to discourage the same type of play in the future, could someone please save the statement for when the same thing happens to Favre, Goober or Romo. I'm sure Polian and Jerry Jones will be ever so understanding and fully support whichever young man happens to "unintentionally" destroy their season.
