I think you might be getting lost on the terminology a little bit. And Bertz is probably making the point you're trying to make. Whether Rizzo grounds out to short right or gets a single, he still isn't getting one of the Three True Outcomes (BB/K/Home Run). It's still just a number in the denominator of 'other plays' (the things theoretically all of us want). As Bertz mentioned, there's definitely an argument it leads to a different approach at the plate that leads to more TTO results. But once the ball is in play and not out of the park, there's no way for it to result in a TTO. I thought that was the point I was making, banning/limiting shifts likely leads to more balls in play that find holes and go for hits giving us the ideal outcome of a non TTO result (a hit vs a GB/LD out in to shifts). They want ways to get more action and base runners, doing this with the shift would lead to that imo. The lowest BABIP league wide, between 2000 and 2019 was 2002 at .293, and the highest was 2007 at .303. Now, 2020 was .292 and 2021 so far is .287, but at most we're talking about one in a hundred balls in play going for an out vs a hit in an era where a third of your outs are coming via strikeout.
