The way I see it the Jays are in a pretty precarious position with Jose and Edwin being FA's following next year. If I'm in charge, I spend large on a FA pitcher to anchor the staff. Stroman looks much better as a #2. Put Osuna as the 5th guy in the rotation. The lineup is fine the way it is with Cola at 1st, and Travis at 2nd (with a built-in backup in Goins). Carry Dalton as a 4th OF but cycle Jose, Edwin, and Cola at 1B/DH when rest is needed. This paves the way to Jose at 1B if you want to resign him for a few years. Shore up the BP with a top end addition and a mid-range addition, so you can use Sanchez there to start the year, but have him available if you need another starter.
Then you let it roll. Things go right, you have a nice shot at the playoffs. Things go wrong (or injuries hit), trade Jose and Edwin and you are already WAY down the line on a re-build with Donaldson and Tulo to anchor your middle of the order.
The one thing we can't afford to be next year is 'fringy' come the trade deadline. That's why you have to go all in with a top of the rotation starter rather than a few good value wild cards. If we are 'sort of in it' at the deadline, keep Jose and Edwin, and don't make the playoffs, its a disaster.
