There are more factors at play, though. The poor player with supposed upside is a full five years younger, he makes $1.5 million less, and he still has three more arbitration years before he can become a free agent. The average player's primary source of value has become redundant with the acquisition of Adam Eaton, and he only has one more arbitration year before he can become a free agent.
For a team expected to compete in 2014 and needs a capable, if unspectacular, leadoff hitter, De Aza is more valuable. For a team looking to gain more from a developmental standpoint than from a wins and losses standpoint in 2014, Viciedo is more valuable.
