There is no definitive answer to whether the league leading quarterback in turnovers has ever won the Super Bowl, as different sources may use different criteria to define turnovers, such as interceptions, fumbles, or both, and may also include or exclude postseason games. However, based on one possible approach, using regular season interceptions and fumbles lost as the measure of turnovers, the answer is no, as of the end of the 2020 season.

According to Pro Football Reference, the following quarterbacks led the league in regular season interceptions and fumbles lost since the Super Bowl era began in 1966, and none of them won the Super Bowl in the same season:

• 2019: Jameis Winston, 35 (30 interceptions, 5 fumbles lost), Tampa Bay Buccaneers, missed playoffs
• 2018: Ben Roethlisberger, 18 (16 interceptions, 2 fumbles lost), Pittsburgh Steelers, missed playoffs
• 2017: DeShone Kizer, 28 (22 interceptions, 6 fumbles lost), Cleveland Browns, 0-16 record
• 2016: Philip Rivers, 25 (21 interceptions, 4 fumbles lost), San Diego Chargers, missed playoffs
• 2015: Blake Bortles, 23 (18 interceptions, 5 fumbles lost), Jacksonville Jaguars, missed playoffs
