From where I sit as a keyboard warrior with the limited puplic information that I have, everything points to Nate Diaz having a management problem.
Mike Cogan is his manager I think... So I'd say yes. 
Yeah It doesn't really seem like Nick or Nate have ever had great direction from their "management"
I can't believe someone hasn't stepped up and offered to be their manager, with the right guidance they could make that elusive "GSP" money so long as they keep winning.
Who do you guys think would make a good manager for them?
