I love Soto's arm, but if I were trading for him, his career walk rate would be a red flag. It's a little better this season, but any scout watching would know that that is only because he's not trying the throw his slider much recently. He's living on pure velo, which is great, but how many more seasons can a 27 yr old guy throw 100? Maybe Greg is a freak and can keep it up. We hope so. But if he loses a couple of MPH he needs that slider and are you then looking at 5.5BB/9IP again?
That's the kind of calculus that you hope doesn't sway a GM if you are trying to trade him!
