Gee, no. If signing Gallo for 1-2 years slows the Sox to re-sign Devers, I think Sox fans will be disheartened.
Did you realize that in spite of his high K rate, Gallo still has a higher OPS+ than Bellinger? Not by much, 79 to 78. But with the fervor that you are arguing for Bellinger, you’d think he was definitively better at something. He’s basically the same as a hitter. Far worse as a fielder. But yes, he does have some more speed and steals a few bases on the rare occasion he actually gets on first base.
Of course, if the Sox need a lefty-hitting outfielder with speed and a 78 OPS+ and a sub.300 OBP, why overpay for Bellinger when Jarren Duran is already here?
