I feel like the Marlins deal was risky, the Dickey deal was reckless, and both moves were ill-timed. If you have to replace 4/5 of your rotation to be "all-in", maybe you shouldn't be "all-in".
To be fair though, I was excited coming into this season, but that was under the assumption that all of Dickey, Johnson, Boni, Izturis, Cabrera wouldn't be terrible.
