The Eagles threw more completed passes over 40 yards this year (20 in 14 regular season games till they rested the starters, 3 in the playoffs) than any other team in the NFL. There were a number of incomplete long passes only because the cornerback interfered with the receiver, or an occasional and inexplicable miss by the receiver.
Obviously you don't watch Eagles games.
I'm guessing that this is "run after catch" stuff from TO and Westbrook. From what I saw in the playoffs, McNabb's deep balls are floaters.
