No, it didn't, and IMHO notin's argument about the Braves having more depth than us explains why it made sense for them, but doesn't explain why it made sense for us.
If we kept Sale and he got injured, obviously we'd have to put him on the IL and fill in for him. That's just normal everyday business in a world where pitchers are dropping all over the place. We lost Giolito and Whitlock for the year, and Bello and Pivetta have had IL stints.
