By the time Miz completes his year, that will be the equivalent of Skenes workload last season.
in another lost season, Pittsburgh wouldnt be any further behind with 1 more, possibly 2 years added to their window. That's sorta the in division trade off. Skenes 3 seasons with Milw(clearly traded final offseason) and Pirates 4-5 seasons having Miz. So they better their chances vs Milw in the division when Skenes departs.
