I think Dickey's option is $12M.
The Blue Jays will need to either pick up Dickey's option or convince Buehrle to return. Hopefully both. They've traded all of the decent upper minors SP depth, so the innings will be crucial. The closest legitimate SP prospects are in Lansing and below so they won't even be serious options in 2017.
Maybe if they lose in the Wild Card game or something like that, Buehrle will be thirsty enough to come back for one more year.
Dickey is on pace for another comfortably above average year, by RA9-WAR. I don't see any reason not to pick up his option.

Buehrle (please)

Trade Saunders for someone? Maybe deal Edwin?
Try to attract Colon on a one year deal? Buy way low on Bud Norris?
Mid-sized deal for Wei-Yin Chen, Mike Leake, Doug Fister, or Ian Kennedy?
I doubt they throw money at a SP like Kuma, Zimmerman, Shark, etc. But they didn't trade all of their SP prospects without some plan for 2016.
