You still need a Backup for C (Martin) and Infield. So not really room for Pompey or anyone else.
Infield would have to be Barney or Goins - no room for both.
Back up catcher - hope they find something more than they have in the org today - may be Navarro would come back cheap.
Of course if you find a sucker to take Smoak and/or Upton and/or Goins. But the the $$ you spent on Morales + Pearce + what you save (if any) on those 3 could cover most of what EE would have needed. EE gives you more flexibility since he can actually play the field whereas Morales will be an adventure at best out there. Too many DH/1B type players.
They will also need bullpen arms (can never have enough) but also some kind of starting pitching depth. Pretty good 1-5 but if anyone gets hurt they are screwed.
Pretty screwed up roster construciton but there's still a few weeks to spring training.
