That debate will get renewed attention in April when Ben Affleck and Matt Damon release "Air," a movie that recounts how Nike signed Jordan.
"A lot of people want to take credit for signing Michael Jordan, most obviously Sonny Vaccaro."
It's unclear if Vaccaro spoke with Knight, Vaccaro, or Jordan or if he relied on existing sources, including "Sole Man," an ESPN documentary about Vaccaro.
Several books and news stories also have recounted how the Jordan deal came about, including parts of "Just do it," "Swoosh," and a sweeping 1992 story in the Washington Post.
Regardless of the movie's spin on events, the Jordan deal was a pivotal moment for Nike.
