Was Billy Sunday from Men Of Honor a real person like Carl Brashear was?

Billy Sunday, a character in the film "Men of Honor," is not based on a real person, unlike Carl Brashear, who was a true historical figure. Brashear was the first African American master diver in the U.S. Navy, and his story is depicted in the movie. Billy Sunday, on the other hand, is a fictional creation used to represent the challenges and dynamics faced by Brashear in his pursuit of honor and recognition.
