I agree with you completely here.
Like I said before, Klinnsman has done a great job bringing in talent, but I can't help but feel he's diluted the pool a little bit; team cohesion is lacking, and I can't help but feel it's due to all the new additions. It's a catch-22 really, we don't want to leave any stone unturned because then we miss out on potential talent, but having a solid, consistent core is also important to success.
So far, I can only recognize Dempsey, Beckerman, Bedoya, Bradley, and Fabian as core players. Every other player has question marks over their heads.
