Yeah Rojas alone probably can't show Nico the door. That said if Shaw has a good year in MLB and Rojas rakes in MiLB it's a bit hard to argue for keeping Hoerner around. Ditto Shaw plus Pedro Ramirez.
The team is currently about $100M under the LT heading into 2027. And while the CBA almost certainly bumps that number up, inflation will keep it close to $100M in 2025-2026 dollars. So I assume the team will sign a FA SP of substance, a FA OF of substance (probably re-signing Happ or Suzuki), do a bullpen spending spree similar to this winter, and have room for one more big move. Whether that's Hoerner, the other of Happ/Suzuki, a second FA SP, etc. depends a lot on who does/does not have a big year in 2026.
