The Oakland Athletics‘ bullpen was the problem in 2015 and the brightspot of 2016 when the rotation faltered, so we are taking a break from position players and focusing on the bullpen.
The players who are pretty much guaranteed to be in the bullpen are Ryan Dull, Sean Doolittle, John Axford, Ryan Madson and Santiago Casilla.
Out of those five guys, each one could be the closer and each one could be used as a LOOGY or in a matchup.
