If this season has shown us anything, it is that we still have major holes in our starting 8. Looking at the roster, I see only McCutchen and Walker being starters for sure. Alvarez will still start but the jury is out if he can become a starter. When Presley and Tababta come back, we will get to see if they can cut it. Everyone else is just a placeholder or a backup.
One other thing we have learned is that strong SP (and BP) can carry us pretty far. So if we can get our SP on tract, we can be competitive until the position players show up.
Lastly, we have learned that some of position players at AAA have value, but they don't look like anything special right now.
