The Bengals restricted the Patriots to just two field goals as they ran out 13-6 winners, ending quarterback Tom Brady's streak of 52 consecutive matches with a touchdown pass just two games short of the all-time NFL record held by Drew Brees.
Brady was also sacked four times by the defense, including on his very first pass attempt, and Dalton says that it was "fun" to watch from the sidelines.
"It's definitely fun to watch those guys go out and play," Dalton told The AP.
"They're doing so many good things, and to see what they do to a guy like Tom Brady and what they've done to a lot of these quarterbacks, they're some of the best in the league. They're playing unbelievable."
The result ended the Patriots' unbeaten start to the season while also improving the Bengals' record to 3-2.
