Jameis Winston last year had 7 interceptions returned for touchdowns. According to the Pro Football Reference website, that’s the most ever. Since the merger in 1970, who is the only other quarterback with 6 such interceptions in a season?
Peyton Manning (in 2001). This is not a stat the NFL officially tracks. The Pro Football Reference website indicates that only one other quarterback has thrown 6 in a season – Rudy Bukich of the Bears in 1966.
