I think if this team doesn't start moving out a few bodies and planning for the future it will be a major mistake that could set them back even further as far as competing again in the near future.
This team can't move runners or hit with RISP, they don't have a whole lot of speed on the basepaths, the defense has regressed a lot, injuries aside the starting pitching as a whole just hasn't been very good, etc, etc.
On the positive side Smoak has surprised and the bullpen hasn't been too bad.
What has been really crappy is the UFA players just being plain awful and making them worth next to nothing in a trade (Estrada, Liriano and Howell in particular).
I still think someone will make a fair offer for Bautista, but he needs to waive his no-trade clause to make that happen.
Really think you have to go beyond those guys and really think about moving guys like Happ, one of Barney/Goins, and maybe Donaldson too if you get an offer that blows your socks off.
I keep hearing people say they need to keep the core together for another run in 2018. Why? How will the team be any better than the 2017 version in that scenario? Personally I think the contention window has shut on the current group and its time to be smart and build for the future.
Next season should be the start of the transition as you can't get rid of all these contracts for older, declining players at once. The team will have to be built around guys like Martin, Tulo and Morales with younger, cheaper players with more upside filling in at some of the other positions.
There are a few guys on the roster now who should not be moved and become key pieces of the future such as Osuna, Stroman, and Sanchez. The jury is still out on Travis with all the injury history and the Dee Gordon rumblings it makes me wonder if he gets moved to a corner outfield spot in the near future. I'd consider keeping Pillar with his great glove, but just wish he would improve with the bat.
As far as losing casual fans go I could care less about those people. I just hope Jays management will feel the same way and do what is best for the team, not for the bottom line. If you do what is best for the team these casual fans will come crawling back eventually anyway to jump on the bandwagon.
