They would just run a 6 man rotation for a bit and have the awkward but necessary conversations with two of Max, Berrios, Lauer about pitching in the pen.
Realistically there is almost no chance this entire group is healthy and above replacement level at the same time:
Cease - probably the only one with an A health grade and is about as low risk as a starter can be, unless you think five straight clean seasons is a downside because of accumulated wear and tear
Gausman - 35 years old, huge workload recently + recent velocity decline scares
Yesavage - weird mechanics, rookie, will have his workload monitored
Bieber - massive injury risk, turning 31
Ponce - turning 32, big error bars on his projections/performance, also had a MASSIVE workload bump in 2025
Berrios - turning 32 this year, big performance and injury risk
Scherzer - 41 years old, chronic injuries in recent years
Lauer - turning 31 and has a 92 Stuff+. If we are being honest he's a swingman anyway.
