Better current performance than Judge/Bellinger/Gallo, although this is by far the least important factor given the sample size disparity
Elite plate discipline, even with power regression Hoskins walks a ton and is just barely over 20% strikeouts in his first exposure to MLB, while Judge and Gallo have severe contact issues and Bellinger walks less/strikes out more than Hoskins. To be fair, all four guys are walking at a well above average pace
Projections prefer Hoskins to Judge/Bellinger/Gallo.
