My view on any sample: it happened. Sox fans should savor Ceddanne, instead of rooting for a minor leaguer to replace him. If Rafaela has an entire good season, but then regresses and fades away, then what -- One Year Wonder?
Consider two other recent Boston outfielders, who each had one All-Star season and won one Gold Glove...
Jackie Bradley: regarded by many as one of the Red Sox' top centerfielders in a sample size that spanned 11 years. Career WAR 16.6.
Andrew Benintendi: also a key cog in a world championship, which his manager says they couldn't have won without him. Career WAR 15.9 in 10 years... and still active.
Rafaela, 24, could outdo both -- but even if he doesn't, enjoy watching his accomplishments. And it's still a crime Anthony isn't in Boston already because the front office cares more about a 6th year of control that doesn't concern 99% of MLB players and their original teams.
