Writer Dan Szymborski is slowly releasing his ZIPS projections for Major League teams and he notes about the Yankees that,
I don’t bleieve ZiPS has ever projected a bullpen to be better than the 2018 Yankees and I don’t believe it’s even particularly close.
And then,
Putting it in less vague terms: ZiPS projects 10 pitchers on the Yankees 40-man as relievers. Their projected ERA+ in descending order: 177, 159, 146, 145, 136, 129, 125, 120, 112, 112.
Wow.
