Not only were they missing an ace in 2022, they lost the 3 guys closest to that role (Nate, Wacha & Hill) and left their replacement slots to Kluber, the returning Sale/Paxton and the converted pen arm in Whitlock.
If you want a great rotation, you have to build from the top- not the middle or bottom.
The next thing you do is add at the top, again.
We added Pedro, but didn't win until we added Schiiling.
We had Schilling but didn't win again, until adding Beckett.
We had Lester but didn't win until adding Lackey.
We added ace Price, but did not win until adding Sale.
We haven't even added the first ace.
