The history of the Boston Red Sox is loaded at virtually every position but everyone has their favorites.
There’s an important distinction between best and favorite. A statistical analysis can provide us with a fairly definitive answer for who the best players are. There may be some debate with different people favoring certain statistics over others but we can generally narrow it to at least a small pool of candidates.
Naming your favorite players is more subjective. Ted Williams is objectively the best position player in franchise history but his heyday was before my parents were born.
