Johnson > Buerhle
Well, duh. But considering how Toronto only has Johnson for one season, I doubt they're willing to part with him for anything less than a king's ransom.
Buerhle and his considerable contract may be a different matter entirely.
You hated Buehrle's contract when the Jays acquired it, citing money owed in 2014 and 2015 as reasons the Twins shouldn't have made a similar deal with the Marlins.
Now you want to give up Morneau to acquire Buehrle.
