I did a look back at the bullpen's preseason projections for everyone who has pitched 20 or more innings this year. None of them were projected to be good, Rodriguez and Hoffman projected to be average. The rest were replacement level or very close to it.
Varland should be average or a bit better based on projections, but he hasn't been. Probably because they messed with his pitch mix.
Little and Fisher exceeded expectations, but a lot of the rest of the pen hasn't. So it's kind of a wash.
