The interesting thing about Gibson is that except for his poor walk rate, his metrics at least superficially say that he's not pitching much worse than when he was effective. He's allowing a much higher batting average on balls in play and his strand rate is worse, but both should theoretically normalize somewhat, and other numbers like his K rate are right on. And then you watch him pitch, and you can see how much more often hitters tee up and tattoo the ball. His home run rate alone is nearly double what it was at his best. At this point he's a cross between the worst version of Kevin Slowey and Charlie Brown when he gets his clothes knocked off by a line drive.
