Looks like they are hot on the trail of Feliz and Zeigler as well.
They need to shore up their position players, but not a ton of weaknesses with this roster.
The problem with the position players is they have to hope Zimmerman rebounds. The other spots are set in stone outside of CF. They don't "have" to upgrade the offense from last year, but that hurts them a bit. Unless they get a stud CF or are willing to replace Werth/ZIm, there is only so much they can upgrade on offense.
Thats why I think they should really attack CF, but doesn't appear to be their plan.
