Well, what was the benefit to keeping Mookie in 2020 and then losing him for a fourth round pick?
In 2020, the Sox season hinged 100% on the health of Price, Sale and Eovaldi. Not Betts. The Sox offense was top four in MLB using any metric you like. Pitching? Not so much. And their Big Three are all expensive and oft-injured.
If the Sox kept Betts, then Price, Sale and Eovaldi are all still here next year. Betts is not. Martinez is not. Bradley is not. And a few other lesser players. Price, Sale and Eovaldi May or may not continue to get injured. But they all definitely get older. The farm system gives maybe a little relief? The payroll is still in the $190-200 mill range. The lineup (C:Vasquez, 1b: Dalbec?, 2b: Chavis, 3b: Devers, LF: Benintendi, CF: Duran?, RF: ??, DH:??) can certainly no longer be called a strength and borders on Marlins-like production. And the rotation is as described.
That team would finish above Baltimore.
But if you enjoyed 2014 and 2015, you might not mind so much..,
