Most important positions in football in ranked order?

ok personally I don't think there is most important position because football is a TEAM sport not an individual sport because if there where no lineman then it would be a crush the qb and running game and if there was no qb then there would be no body to throw it to the wr or give it to the rb and if there was no wr or rb then there would be no body that the qb could give it to and I could keep going on if you want and do defence too......
