His bat would be a very slight nice to have for the bench, but the 'why' always has been and always will be the goodies that would come with him. You'd presumably be getting Robert Hassell or Luis Campusano, either one being our clear #2 prospect, and an MLB ready SP in either Chris Paddack or Ryan Weathers. Hosmer + Campusano + Caratini + Paddack + Weathers + Gore for Contreras + Bote + Alcantra + Mills. According to MLBtradevalues, the value comes out pretty even. We get a lefty bat, a cheap backup catcher, a future catcher, and pitching, they get infield help, a starting catcher, a SP, and get rid of Hosmer. Need to get a third team involved
