Meh...I think there is a fair bit of that stuff everywhere. Seattle's is, by far, mor publicized than any other defensive backfield (and yes, I do understand they are at the front of the naughty line).
My whole point in the other thread is that despite the NFL being inconsistent with this call all year with all teams, a point I will concede, they have been pretty damn consistent in letting Seattle's DB's do what they do. The refs did not swallow their whistle in the playoffs or Superbowl, they let the stuff go they've been letting go all year. To me, that's consistency, even if it does not fall in the perameters of the written rule.
