That's a false choice though. The Cubs have, COVID aside, always spent right up to the LT line. We have good reason to expect they're going over it this year, but we *know* Jed is going to spend at least $40M this winter. We also know Jed is very conservative in regards to pitching depth, so it's silly to think a SP addition isn't earmarked for (it's pretty clearly the 2nd biggest hold on the roster after 1B).
Jed might miss on one of the lefties, there are only three of them after all. But the realistic worst case scenario is like Bieber or a Stroman reunion, not just letting it fly with Wicks and Assad both in the opening day rotation.
