That's a good one too. He also doesn't have nearly the cache or reverence in the industry that Nas or Rakim does. Partly cause he's white, partly cause he's a recluse but other mc's don't metaphorically "bow" to him like they do Nas.Only other person who I think might have had the inclination would be Eminem, but he's too beholden to his label and sales numbers to ever make independent moves like this.
