Mike Morris, never, ever care what some fan site junkies (me included) think. The only people that matter in this are you and the team you want to join. Good luck and hope you end up a Cane at the position you want.

From my perspective, I think you take athletic freaks and let them battle it out at the position of their preference. If Richards wants to play RB let him take his crack there. If Morris wants to be a DE, let's see what he can do. It's great to have kids with this type of athletic versatility. That's how you end up with guys like Deejay Dallas or Rousseau.
