Nobody here or elsewhere is picking the Red Sox to win the '21 World Series, but since this is the realistic thread: are the Sox, set to open with half a lineup of platoon players, THAT much worse on screen than the favored Yankees?
To help answer, here are quick match-ups of the two rivals... 1B and 2nd go to Voit and DJ, no questions asked. But X is a better shortstop than Gleybar, and though Urshela is solid at the hot corner, would any GM turn down a straight trade for Devers? Nope. Frazier and Judge rule over any Red Sox corner outfielders, but in center, Verdugo at 24 > Hicks at 30. Behind the plate, NY has a guy they don't even want behind the plate, so Vazquez wins easily over Sanchez. DH is a pick-em, but here are three-year OPS in the Bronx and Beantown: Stanton .860, JD .938. Both starting rotations are full of questions marks, but the Yanks have Cole. New York also has an edge with their greatest bullpen of all-time (the one that keeps keeping them out of the World Series every postseason).
While some Yankee fans may strongly disagree with the above ratings, realistic fans know that every position but second base could go either way this year. The Yankees are certainly better, but they just better hope Cole stays healthy. The doormats aren't realistically that far away from the AL's heavy favorites.
