No. Not "after the fact."
I hated the trade at the time, and said so repeatedly.
I do think we could have used another starter, but it was not essential. I said that at the time too.
When the league offered a give back, I said we should do it, even knowing we were past the trade deadline, and it meant we'd have to finish the season without Pom.
Something did not "have to be done", At worst, we could have traded for a 5th starter tyep for less of a bounty/
