Talk about selling your soul to the devil! Up until about age 34, Dickey wasn't even a regular starter. I don't even know if you'd call him a mediocre pitcher. His numbers sucked. Then, suddenly he drops his era below 3 consistently and wins a Cy young at 38.
Who DOES that? Guy suddenly becomes a stud in his mid thirties. I've never seen a stat sheet like that. In any sport.
As much as I want more pitching depth, I would not make this trade. Not for the names that are being mentioned. No way.
