about the "cheating" that probably most teams did, but only the Patriots got caught doing...
That was two or three games into the 2007 season. They were caught and then it stopped. The NFL, no doubt, was watching them like hawks.
Even though it stopped, they still went 18-0 and would have had a perfect 19-0 season, winning the Superbowl against NYG, except for that one extremely lucky catch by David Tyree with less than 2:00 left in the 4th.
As for what happened in the seasons after, remember that Brady's leg got mashed in the first game of the 2008 or 2009 season and a relative unknown, Matt Cassell, took the team to 11-5 or something like that. And this was after the "cheating" scandal had been exposed and the NFL probably still watching them like hawks.
People laughed at some of the "old" players, who did end up leaving. They got younger players. Rookies. Still had better than .500 seasons in spite of the rookies and in spite of being closely observed for any further signs of "cheating".
So just wanted to point out that, after that whole episode, some more honest teams admitted to having done pretty much the same thing. They just never got caught.
Anyway. From all the sports articles I've been reading since Sunday, it looks like even though Las Vegas has the Pats as 3 point favorites, the articles themselves make them look like the underdogs due to their crappy Defense. The mantra is that "Defenses win championships".
If that's true, then the Giants, with a vastly better Defense, are not the underdogs.
