If there really was a conspiracy and the refs (or players, coaches, whatever) were in on it, you really don't think there would have been a leak by now? You're talking about a sport where there are literally cameras everywhere, 24/7 news coverage, and everyone's constantly looking for the next scandal.
This isn't the WWE, the NFL represents itself as an honorable competitive sport. One leak would completely destroy everything they've built, and then nobody's making any profits. Why risk it?
The point isn't that it's a massive conspiracy, but rather a few refs and a very few in the NFL Commish office.
It takes very little to sway most games. Since holding happens on every play pretty much, if they want to keep it close, they can always call holding.
I can't tell you how many holding flags I've seen called after a deep ball was caught. They didn't call it at the time of the hold, but waited to see if the pass was completed. That is very suspicious.
Moreover, the coincidences can be very hard to overlook. I think I said it in October or November that there was no chance anyone other than the Patriots were going to win after 9/11. You don't really have to look further than the Tuck Rule game against the Raiders for a greater example. I don't think the NFL expected Belichick to cheat as hard as he did nor to exploit the "let them play" attitude of the refs as much as he did in the Super Bowl, tho. Same with NO after Hurricane Katrina. Bettis, Ray Lewis, and others getting rings and riding off into the sunset, etc. The number of coincidences seem odd.
I think as the season develops a narrative starts and stories emerge and I think the NFL guides it. Do I think the NFL wanted the Rams in the Super Bowl against the Titans? Nope. But those Rams were simply so good that they often scored 40 in spite of bad calls by the refs. Same with the Titans.
it's like this: if there's manipulations it's just that...manipulation. I don't think it's outright fixing. That said, so often it only takes a call or two on critical plays to sway close contests. How many teams have gone 6-10 that could easily have gone 10-6 with literally one call per game going the other way?
I don't think there's a grand conspiracy nor game fixing, but it wouldn't surprise me to find out that there's been tampering. I already believe that now.
But yeah, for the most part the game's clean and if after decades of being crapped on (in no small part because of the owner), then it doesn't hurt my feelings if the winds change and we get the wind at our backs for a spell.
