Playing Outside Linebacker or Defensive End

Fritz Shurmur's description of how to play the outside linebacker or defensive end whichever you call it, maybe the best I have read yet.  I just got his book today The Eagle Five-Linebacker Defense, and was thumbing through it and came across his outside linebacker description.  Unbelievable!  I can't wait to read more, but need to finish the Lombardi book first.  I must be ADD.  I've got 15 defensive football books on the coffee table.
