Playing time is the key issue in my opinion. Even though Rodriguez is more valuable I am fine with Outman making the 26 man roster to start the season because Rodriguez or any of the better prospects need to play every day. Outman can be used off the bench as needed. Sooner than we'd like a starting outfield spot will open up.
This is true of all teams, the best players generally play SS but when they are drafted and play on much more competitive teams many of them switch positions. Teams draft a lot of SS that they know will not end up there.
