Fitz basically won the Super Bowl vs the Steelers in the second half. But then the Steelers #1 receiver won the game with a spectacular catch in the waning seconds. At the time Holmes looked like he'd become an AB-like receiver here, but succumbed to the ganga. But that game was basically a two-fer of big WR plays.
The point isn't the Super Bowl itself, it's what the basis and focus of most modern offense today, and in particular what teams (and TV) think that people want, and it's passing and high scoring.
The impression is that running backs are the ditch diggers of the offense, you need them, but nobody is going or tuning in for a game with two 150 yards off tackle rushers and 8 yards in pass completions. I'm sure most coaches actually hate that, (esp. Duz for example) but they know what gets hired. And GMs and owners think they know what brings in the masses. Of course, winning does that better, but only one team (usually NE of course) can win.
