You may be right, but New England has nothing to complain about. The NFL has gone to such great lengths to scrutinize every single bit of contact between receivers and defensive backs in the last couple of years specifically because in big games the Patriots' defensive backs were known to "push the envelope" on the rules regarding downfield contact.
It's gotten so damn ridiculous that a cornerback with no arms could probably play in the NFL these days, since the position has become so heavily regulated.
Very good point. The Patriots have reaped a lot of benefit from pushing the envelope in big games since officials tend to call big games a little looser.
