Pretty much agree with your synopsis. Looking ahead, with Papi gone, Hanley does not appear to be the answer at Designated hitter so we will probably try to sign a FA that has a proven power bat. Young may be gone next year. It is not a stretch to imagine either Benintendi or Swihart in left field. I don't believe Swihart should catch except in an emergency. Holt will probably remain a utility guy. Moncada will probably come up in August and whether he fills in at 2nd, third or first base, he appears to be ready to stick in the majors. It would be a young team except at DH with quality at every position but even so big Papi will be sorely missed.
Next year the 3 starting pitchers who look to be keepers are Price, Wright and Porcello. Where do you find 2 quality starters?
