If the Red Sox did that?
Since the 2019 season, the Red Sox have added Perez (twice), Pivetta, Richards, Gossett, Mazza, Godley, Seabold, Whitlock and now German. Sure they are not all star pitchers, but let's not pretend they have been inactive on that front. Getting Sale and ERod back should be a huge boost to the rotation.
We'd all like it to be better, but that does not mean it is not already improved.
And some of those Jays' pitchers you mention are already off the team, correct? Taijuan Walker, for example...
