Why do athletes get hurt more on turf vs natural grass?

In this episode, Zach Guiser and John Tropeano kick things off with a discussion about the staggering physical and mental excellence of Taylor Swift's 149-show Eras Tour.

They then pivot to a new, in-depth format, tackling one major question: Are artificial turf fields more dangerous than natural grass?

Zach breaks down the scientific literature, explaining the difference between minor injuries and the catastrophic, season-ending injuries (like ACL tears) that are more common on turf. He explores the "Traction Theory"—how the high friction that improves performance is the same thing that increases risk. The conversation also covers the major exceptions, like lower concussion rates on turf , the financial incentives for teams, and the ultimate trade-off athletes make between performance and health.
