Yeah I'd rather have Smoak too but if they go with both Thole and Navarro, there will be a bit of a squeeze where you have to do one of the following configuations:
Thole, Valencia, Smoak/Navarro, Goins
(in this scenario, Travis and Smoak are esentially the 4th and 5th OFs and Tolleson is DFA'd and Pillar probably goes back to the minors when Saunders comes back or someone has to be moved)
Thole, Valencia, Smoak/Navarro, Tolleson
(in this scenario, Tolleson isn't DFA'd but Pillar still has to go back to the minors when Saunders comes back or someone has to be moved)
Thole, Valencia, Goins, Tolleson (Tolleson is basically just there because he's out of options and can sort of back up the OF. Either he gets DFA'd or Goins is demoted when Saunders comes back)
Thole, Valencia, Goins , Gindl(in this scenario, Tolleson is DFA'd but you have a true backup OF who you can demote when Saunders comes back, one of Smoak or Navarro has to go now though)
