The Jays have 2 rotation openings in 2018, plus practically no depth in the minors. Koehler will be lucky to get a big league rotation job elsewhere, but even if he wanted to test the market, this team is probably the best fit for him if he realistically wants big league starts next year. Hell, if he leaves, he leaves, no big loss, but I could see the Jays trying to bring him back to act as depth.
