I'm trying to find out a movie title. Or it may have been a story in a TV anthology. It was a about a dark sisinster man who has a vendetta against another man. He is making his life miserable. The man's son gets some of his friends from the football team to intimidate the sinister man intpo leaving his father alone. The sisnister man easily disposes of the football players and then turns his attention to the son.

This was on TV in the early '80's.
