When we beat the Ravens on MNF in 2011 - many folks who saw it on TV called it "boring." (12-7)
I think you've hit the nail on the head with this statement, NYC.
Perception/excitement from watching games on TV versus Attending games is quite different (for most).
Watching a defensive struggle on TV is far less exciting than a high powered "shootout." On the other hand, attending games that are defensive struggles, the crowd is extremely loud and pumped. The atmosphere in and around the stadium is quite a bit more "electric."
That definitely holds true to the games I've attended (mostly in Cincy). The crowd there gets frenzied in a tight defensive struggle.
I don't really buy into "exciting high powered offenses is what succeeds in the playoffs either. Results have typically shown the opposite (IMO).
