It doesn't necessarily have to be those guys, but there's an opportunity to rethink how bullpens work in the age of 5 inning starters. Most teams have been carrying 13 or 14 pitchers, which generally works out to 5 starters, 7 or 8 one inning guys, and a multiple inning mop up guy. In the Red Sox case, the multiple inning guy has been really good and not used in mop up situations. If you can find the right players, it may work better to have 5 starters, 3 decent or better multiple inning guys, and 5 one inning guys. You'd be able to give the multiple inning relievers 2-3 days off between appearances and you'd have one available every night.
It may be possible to stretch out a one inning reliever to become a multiple inning guy. Or maybe you use young starters who haven't been built up to a full starting load or don't have a decent third pitch. If you could build a staff like that, I think it would work better than the current situation of having 4 or 5 different pitchers appearing in every single game.
