It's been interesting hearing how many people have been asking whether it's time to replace Soto with Fulmer when, in terms of production, maybe the better question is whether Lange should get a look at the high leverage/closer role.
Either way, the bullpen is legitimately much better than last year (adding Chafin, Lange/Vest have been an upgrade over Cisnero/Funkhouser, Peralta is actually a reliever, etc.), but Fulmer and Soto being question marks isn't helpful at all. And both are contributors to the high xFIP numbers.
