Stuff+ doesn't look at if a ball is a strike or not. What good is having incredible Stuff+ numbers if you have a WHIP of 1.500. I'm sure Fujinami has great Stuff+ numbers but we all know he can't pitch. I have no idea what PitchingBot is, but Kopech's FIP is 5.67. His xERA is 4.26 and the statcast models do not LOVE Kopech. His Pitching Run Value is negative for every pitch he throws. He's well below average in every area except for xBA, Fastball Velocity, Whiff%, K% and Extension. Every other model is below average to poor. He's prone to giving up HRs as well.
