Jose Bautista is not a bad Plan B option if Dexter Fowler can't be signed. Signing both I think would be ideal, since it would only cost money instead of prospects.
I think if the Jays fail to sign Fowler, don't retain one of Bautista or EE, and fail to make a big trade for Adam Eaton etc., that would be a huge PR disaster. They need to at least sign one of those players.
Lineup with Fowler & Bautista would be pretty darn good:
RF Fowler
3B Donaldson
LF/DH Bautista
SS Tulowitzki
1B/DH Morales
1B/DH/LF Pearce
2B Travis
C Martin
CF Pillar
If they can't sign Fowler, then I hope they could trade for either Adam Eaton or Jarrod Dyson.
