At some point that talent level has to become a reality. It just can't be year after year of saying "he has TOR potential". IMO I don't think it ever manifests itself. Even when he is one he hasn't shown the ability have the necessary control to work late into games. He has great stuff but he is his own worst enemy when it comes to control and command.
At this point I think we are seeing what Edinson is going to become. A guy who has stuff that can dazzle you but never fully puts it together.
