Musings on Rule Changes and Bullpen Construction

Starting next season there are two new rules that affect most of the season:

1. Active roster size expands from 25 to 26.

2. Any pitcher who enters the game cannot be removed until the first of these three events:
- injury
- end of the half-inning (or game)
- they have faced at least 3 batters.

As the offseason begins, what do the new rules - the second one, specifically - mean for the Red Sox bullpen?

Options Are Few

Boston has two 25-man roster spots open, but several more than two to fill.
