I was involved in a rewrite where it would have been much easier to refactor the old system.

A year into the process one of the c-level leaders pulled me into a room and asked why I couldn't fix the legacy code, and I basically told him that he should have pushed back on it. I couldn't fix the legacy code because that would be months of refactoring that should have been done instead of the rewrite.

Context: the legacy code had some design flaws that required major refactoring, but the legacy code "worked" except for very large deployments. The only problem was that the legacy system wasn't modular, so it didn't have unit tests and wasn't cross platform. All of those problems are easier to tackle via refactoring instead of a full rewrite.
