If that were the case, why was Quinn allowed to finish out the year with the door open to returning next year? If Dolan wanted Quinn gone, he would have been gone and Martin or Knoblauch could have finished out the year. It makes more sense to me that JD fell on the sword for Gorton.
I've believed this to be the case as well.
But I don't know that the door to "keep" Quinn was ever really open. It may have bee Dru doing his best to shield his friend from the inevitable in the midst of chaos and the players from even more of it.
