The Pats benefited from whistles being swallowed on PIs, until they stopped being swallowed.
That's the main favor I recall them getting from the refs.
Even that was never all that consistent, e.g. the Tebucky Jones fumble recovery for TD that was called back due to McGinest doing to Faulk what he'd been doing every other play too.
The one true favor on the tuck rule is that the film wasn't all THAT conclusive, so the reversal may have been payback for the ref just forgetting the rule existed, or else for missing the roughing the passer, both of which aren't technically reversible. But that wasn't favoring a team so much as it was doing what is both right AND personally expedient, by correcting your big blunder while you can.
