Would we have felt better if it were Pan instead of Klassen in that trade? I think I would have since I'm such a Klassen fan, but I don't know about others. I haven't seen Pan reported as high as triple digits, though. I can't recall, does Pan have a high-effort delivery? Klassen throws 97 pretty effortlessly, at least to my eye.
Pan video. Balance is awful after his release in many pitches. One was 99.
