The NFC West side, led by the first-year quarterback, came from 23-10 down with less than 10 minutes to play to win by a single point.
Wilson told KIRO-AM: "I definitely feel like the Patriots game's when we really started to click. That was a crazy, crazy game.
"To come back and win like we did, against a quarterback like Tom Brady, who I have so much respect for, it really started clicking after that.
"That game gave me some credibility and it showed me that coach truly believed in me."
The Seahawks went on to secure a wildcard place in the playoffs.
