Right now is not the right time to trade Dickey. When you have an offensive Juggernaut like this, then you need to offset with consistent pitching. I am not big on our rotation but it is consistent, with potential of being above average. Bullpen is the right course of action here.
No point in speculating but suffice to say AA is having a dream offseason. So far he has acquired a Future 2B, best catcher on the market, and arguably the best overall 3B in the majors. Now its time to solidify and not get more power. Instead focus on depth and healthy all around solid options. The bullpen requires work though.
