What is the Sabres Greatest Hope of a Bright Future?

Well when we sucked before we latched onto Eichel and Reinhart. Then we latched onto, well some of us, Byslma leaving; others onto Murray leaving. Now I'm asking, what do we look forward to as the finish line for when this team will be good again? What are we waiting for? Mittelstadt? Dhalin? A competent and strong farm system that grows and wins together?
