So your hypothesis is that football fans don't crave instant analysis of the game immediately following said game?
Text me when you realize that you have pretty much missed the last 40 years of how football is fed to the mass audiences and also missed how folks consume and discuss analysis of sports online.
Quibble, I must: "Football fans" is too general. Fans of specific teams crave instant analysis of wins, immediately following said win. Maybe - maybe - fans of the losing team are also interested in an explanation for why they lost, especially if it was close or "lucky", etc. But half the fanbases turn off the TV and go for a walk/drink a beer/do yard work angrily after a loss - they don't consume instant analysis (or any analysis, really).
This is the long-term consequence of parity, and the NFL's strict adherence to it as a guiding principle. Certain fanbases - New England, Seattle, Pittsburgh, Dallas, Denver, and Philadelphia more prominently than others - crave instant analysis. Not coincidentally, those are also the most successful, and consistently good, franchises in the league. Conversely, fanbases in Cleveland. Jacksonville, Buffalo, and Tennessee do not seek out and consume content in the same way.
Despite the NFL's best efforts, there is not "parity" as they would ideally define it; there are many "haves" and there are a few "have nots", but mostly there are a bunch of flabby, plobby teams in the middle, floundering around. Winning one week, losing the next two. Maybe making the playoffs every couple seasons but then backsliding and not actually competing for a championship.
There are only a few markets where team-specific content and analysis is consumed in the same voracious way after a loss as after a win – and they are almost all on that first list: the one with the consistently good teams. Nearly half the NFL is irrelevant on the Monday morning after a loss: fans are not consuming content nor seeking out instant analysis of what went wrong (again) this week. Only in a few, privileged markets, is there interest win-or-lose. (NOTE: Fantasy is a whole other beast - and is absolutely somewhat responsible for the decline in interest and ratings - but it's a different topic, and business entirely).
The fundamental problem for the NFL is that they cannot feature their "haves" every week. Well, they CAN with Sunday Night Football, which is why their ratings for that product remain strong and probably always will. Flexing the Eagles @ Giants game to Sunday night features two "have" franchises and fanbases, which provides the secondary market of content consumption from Monday-Friday of the next week. But the NFL seems to have miscalculated massively with the Thursday Night "package" - both in that it features every team (and some horrendously shitty, uninteresting matchups like Titans @ Jaguars) and the product is just crappier (because of many, many reasons). And unlike the good old days, this same problem seeps into Monday Night Football as well - inflexible matchups featuring shit teams, playing shit football, with teams most of America knows aren't good and has no rooting interest in (except for Fantasy, of course).
Football has had a good, winning strategy for feeding fans for "40 years" but the by-products of that system have resulted in some obvious problems. The proliferation of other entertainment options was inevitably going to cut into the NFL's near-monopoly on Sunday afternoons, and the weaker numbers this season show that nothing can grow forever. To their credit, the NFL saw this coming (sort of) and tried TNF and international expansion. But TNF has backfired on almost every level and it remains to be seen if the game can be sold to international audiences.
That all said, the biggest single problem remains that just a few fanbases are interested in what the NFL is selling: fans in New England, Seattle, Pittsburgh, Dallas, Denver, and Philadelphia consume content like crazy, especially when they win. The rest of the NFL fanbases are not nearly that interested, or crazy. And since parity is "how we got here" I dunno that the NFL has a viable way forward. Eventually, when Belichick leaves, New England will stop being good. Is this a "good market" for the NFL or is this a market the NFL has benefited from that is sports crazy (and fickle as fuck)? If the Pats win 3 games some season soon, are the fans here going to remain as crazed for content? Or will they migrate to the Celtics or Red Sox? And more importantly - when New England falls off, is Jacksonville gonna pick up the slack?
