You start your persuasive essay on college football with these words adapted from shakespeare: "friends, students, mavericks, lend me your ears! i come to bury football, not to praise it." do you need to cite the original source of the quote?

I think that out of courtesy for Shakespeare the original quote from the play Julius Cesar could be mentioned but since it is a paraphrase of the quote and not the exact words spoken by Mark Anthony then I think it is not absolutely necessary to cite the source.
