Dickey was potentially a cheap ace (as it turns out he was more of an innings eater but there was reason to believe he wouldn't age normally). The rationale for the Dickey trade was solid in context. The problem was the context in the first place. AA's decision to go all in was a huge strategic blunder and Dickey is just one element of that more fundamental mistake. If it had been the right time to go all in, the Dickey trade could have been like the Jeff Kent trade even if Dickey wasn't quite an Ace, he could have been part of a playoff run on a better team. The real issue is going all in with a mediocre team. Why? They weren't coming off a good season. They had too many holes to think they could fill them all in one off season and some of the attempts to plug holes only opened up other ones (that disastrous Cleveland trade).
