Seton Hall surveyed 706 Americans across the country, via landlines and cellphones, from Jan. 29 to Jan. 31. The first question asked people how closely they follow the NFL. Of those who said they follow it “very closely,” a group the survey identifies as NFL fans, 16% said they won’t watch this year’s Super Bowl. The poll has a 3.8% margin of error.

Rick Gentile, director of the Seton Hall Sports Poll, calls 16% a “significant number” that “should be a concern to the league, the broadcasters and especially the advertisers.”

The poll didn’t ask those why say they won’t watch what their reasons are, but the political controversy that overshadowed this football season is almost surely a factor.
