Everyman has the tendency of making impact in this world, although not all eventually do. A covenant was upon Isaac, which was passed to Jacob and Jacob needed to pass it to one of his children, it then landed on Joseph. Why Joseph? Why not Reuben, Levi, Simeon or any other child? The other children were able to make impact through their generation, not directly through them. Only Joseph made himself available to carry the baton, which the generation of the other tribes later enjoyed. Genesis 49.
