One thing Breen didn't point out here. If JT is saying this:
“I think the substance issue is real. I think pitchers are using a lot more substances now than they have in the past,” Realmuto said. “Not just a lot more, but it’s been more effective than it has been. Guys are increasing their spin rate. That’s why there’s so many walks and strikeouts every game, because guys are just letting it rip with all the spin. It’s harder to control but also harder to hit. I think if they fix that idea that could help a lot.”
Some of his own teammates are likely among them. (In the same article Bauer says he thinks 70% of pitchers do it).
