Great article on how the Raiders shut down Gronkowski.  Granted, that still leaves teams to cover Hernandez, Welker, Lloyd, and Gaffney now, it's still thought-provoking on how teams could try to use this.

Then again, I trust Josh McDaniels to do some interesting things with all of the weapons he has.
