The only SB I think that was fixed was the Seahawks/Steelers game. I think this year, one of the refs came out and said the bungled calls that helped Pittsburgh, and refs dont usually admit their mistakes.
Also, the Celtics were ok, but they didnt make the playoffs in 06 or 07, and then won the title in 08. That doesnt mean it was fixed (Boston signed a defenseman and a perimeter guy and their PG became a stud) but the Celtics werent anywhere near the top of the East before 2008.
There were bad calls both ways in that SB, but nobody ever remembers bad calls that favored the losers. There’s at least 1 rough call every game, and more in the playoffs because they still “all star” the officiating crew rather than keep the team together. 20 years now various commentators have been complaining about how the NFL picks the officials in the playoffs and they still won’t listen.
In the free agency era 3 years near the top is a good run. Remember the Lakers weren’t near the top of the west before 08 either. Then both teams started peaking, which is why I said it seemed kind of inevitable, both teams started getting really good, Celts win in 08, Lakers in 09, something was bound to happen in 10.
