Oh, come on, you give them far too much credit... fixing a game in order to hype a re-match which might not even happen?
For that matter, having an undefeated team in LA would be a HUGE storyline...every week would be a “1972 Dolphins watch.” From a purely business standpoint, if the NFL wanted to “fix” all the outcomes, they’d have big winners in all the big cities. The Jets and Bears would be perennial winners... and quite obviously they’re not.
Also, New Orleans is (comparatively) tiny, it’s got 370k people, it’s like the 48th largest city in the USA. Los Angeles at 4 million is about ten times bigger than little old N.O.
The NFL would have every reason in the world to hype up LA instead of NO... to suggest a conspiracy in favor of N.O. seems illogical. IMHO.
Edit: As I’ve said before, yes, I do believe individual teams cheat. Patriots deflate footballs, steal playbooks, videotape practices, and so on. And yes, I do believe the NFL downplayed or even covered up some of the Patriots cheating because they didn’t want the bad publicity. And yes, individual players cheat and take steroids and HGH and so on.
But systematic game-fixing? I see no evidence of that. The NFL wants parity and close games, but I don’t think they are stupid enough to try to predetermine games. If they got caught match-fixing, they’d stand to lose billions.
