Part 3/10:
Many fans hoped that the Mariners could replicate their postseason roster exactly next year. However, the reality is that the starting lineup from Game 7 of the playoffs will almost certainly not be the same as Opening Day of next season. Player movements, contract statuses, and development mean that a complete repeat of this year’s team is impossible.
This does not mean the Mariners can't compete next year. But it does mean they will likely need to adapt and rebuild to some extent, especially with regard to key personnel.
