Gose or Pillar should replace Rajai (great fit but not really necessary anymore). I imagine the fifth spot in the rotation will be an open comp between Happ, Drabek, Hutch, McGowan, Stroman, Romero, Nolin and Redmond. The rest should be in AA/AAA as injury depth. The Jays should look to add at least one front end guy to the staff (Morrow, Buehrle, Dickey) for next season.
AA will have to go outside the organization of he wants to improve the C and 2b spots. Which are must improves for me but I could be convinced Kawasaki would be fine at 2b if enough changes are made elsewhere on the roster.
