We need a power upgrade and have 3 obvious positions to choose from:
1B
2B/3B (Mayer at the other)
DH
If we could find a taker for Masa at a savings of $5-6M x 2 years, then pay $30+M for Schwarber, the net cost is about $25M.
I also see Casas as the heir apparent DH, so I'd prefer a 1Bman, but Schwarber and Casas could share horrible defense stories at 1B, going forward.
The gain from Masa to Schwarber or Alonso (Casas to DH over Masa) would be enormous, especially in terms of power.
