Why in the f*** would this be a good idea? Stroman has already contributed 2+ WAR. That means he's having as good of a season as guys that are more established (like Yovanni Gallardo, Justin Verlander, Matt Garza, Ervin Santana, John Lackey), for a fraction of the cost - and in about half the innings pitched.
I'm really glad you're not the one being paid to make these decisions.
