In 2014 Rafael Soriano was the primary closer. He had 32 saves. Drew Storen had a monster year in 2014 as the primary setup guy. He had 11 saves, 20 holds, an ERA of 1.12, WHIP 0.976.
Tyler Clippard was on that team also. He had a 2.18 ERA.
They also had Craig Stammen, Ross Detweiler and Blake Treinen with a 2.49 ERA.
That, boys and girls, was a bullpen.
Except Drew Storen was the closer in the playoffs. So, no, not the best team.
2017 had Doolittle at his peak, Ryan Madsen, and Matt Albers. They had 5 all stars, and Rendon was snubbed despite hitting .301/.403/.533 ("do you go to fangraphs at all?"). Scherzer won a Cy Young and we had a healthy Strasburg in the playoffs.
