Well, if the Sox pitchers never got hurt, trading Mookie might still be on the table, as the team would still be extremely expensive. But more important, let’s not pretend these injuries were not foreseeable. Sale ended 2018 having problems. Price has been off and on with injuries for the previous 2 seasons. And Eovaldi is always hurt. Sure, maybe 2018 was just a stroke of bad luck where the 3 combined for less than 60 starts. Or maybe this is what they are going forward.
Trading Mookie may or may not work out. But if you don’t, and you go for it in 2020, then you delay reset for a year and lose Mookie forever. If the Sox trade Mookie and reset, there is at least a chance at bringing him back.
Of course, trading Price does the same thing. But it’s a lot less likely to happen, and still might be more costly...
