One could expect Betts would decline after such a great 2018 season, but he was still in the meat of his prime. Did anyone expect a decline from 10.4 fWAR to 6.6? JD's was more expected, but again, by this much? 5.9 to 3.2?
Beni was not expected to decline as he approached prime. He dropped from 4.4 to 2.0.
Sure, Bogey and Devers did better, but here are some more drops- expected or not:
Sale 6.2>3.6 (in almost as many IP)
Porcello 2.4> 1.8 (kind of expected)
Eovaldi 1.5 (in a partial season) > -0.3
Pearce 1.2 (just with the Sox) to falling off a cliff
