Pats scheme with their offense, too
Against the Colts' Dwight Freeney, the Patriots used a lot of multiple-receiver sets and put a receiver or tight end in the tight end slot to Freeney's side. As he was releasing and getting into his route, the receiver or tight end would chip Freeney and knock him into LOT Matt Light. This is just another example of Belichick's attention to detail and ability to adjust his schemes to take away an opponent's strength.
The Patriots' defense gets a lot of credit for using different alignments and schemes to keep opposing offenses off-balance. But their offense does many of the same things to opposing defenses, running a variety of formations with different personnel groupings.
