It could be that they just have not been shown it by the young Ravens, specifically the Sophomore class. I agree, there is an element of the unknown that exists or to be "proven otherwise" Perriman, Dixon, Moore are on the hot seat, maybe not so obvious Alex Lewis, Nembot, and even Keenan Renolds. All of them have seen limited playing time (exception of Dixon). This year that is going to change, could it be in the making? Though not seen last year, the TE position could very well emerge as a sleeping giant. Woodhead in the backfield could be the X-Factor that allows the deception needed for a talented TE core to show its effectiveness. Some one has to cover the crafty RB, here presents the TE already deeper than 5-8 yards into the defensive backfield and missed in coverage, Boom! or the Slot receiver that is just one more player than is coverable in Waller/Woodhead/Moore. Though coaching is very important, absolutely hunger for excellence within each player is critical in pushing them above the crop. Thus , the possible "fear" element as a team. As far as a QB casting fear, as posted by some, I think that needs response by defenses around the league. I'm not sure they agree to what critical method one would describe fear. However I can tell you that from what I have read, most players and teams have tremendous respect for Joe Flacco's deep ball and passing game in general.
