In a typical year, a team uses 10 different starting pitchers. So it is likely as of now we see Thompson, Hutchison, Lawrence, and Hatch starting games at some point. 3 of these guys suck giant balls. So, with the rest of the team in great shape, for adding to projected WAR, SP depth has to be the current priority before the season starts.
Injuries happen to both MLB guys and your depth guys during the season.
As I said, I expect the Jays to add more, and better, SP depth. During ST, guys do become available and trades are made.
It really sucks we couldn't retain Chicken Strip.
