1. There are no low-leverage-only spots in a modern bullpen. When the expectation is 3 or more relievers EVERY night, and many nights 4 or 5, every reliever is going to be pitching in high leverage situations. Often. It can't be avoided.
2. Duffey zoomed up out of nowhere in 2019, close to that in a short 2020. Went back to normal when "grip enhancers" became a thing in 2021. Perhaps unfairly, I'm suspicious.
3. Duffey is bad, but I don't think there are 7 or 8 consistently better options in the organization,
4. I keep asking for bullpen talent every winter, and I keep reading reasons why they don't need to add...well, this is what you get.
