If they sign them both, is this your regular lineup?
Hernandez 2B
McCutchen LF
Harper RF
Hoskins 1B
Machado 3B
Herrera/Quinn CF
Segura SS
Alfaro C
If it is, that's as good a lineup as the BoSox or Astros I think. And Kingery as an IF super-sub, I might keep Franco to sub 1B/3B. Leaves Williams and Altherr fighting for an OF spot, and Knapp as backup catcher. 12 man pitching staff.
Some trade possibilities exist for a BU catcher and another starter.
