Expectations too high for Barnes?

Harrison Barnes may have started 81 games as a rookie last season, but it wasn't until filling in at power forward for an injured David Lee during the playoffs that his game really took off. That's a big reason why expectations are high for Barnes heading into next season. But for a player who will now head to the bench with Andre Iguodala on the roster, might those expectations be a little too high for the 2012 lottery pick?
