Re: Wil Myers to the Rays
From a pure talent perspective, this isn't a horrible trade. Shields is a solid front of the rotation arm and Davis is probably an above average 4/5 starter with the potential to become a decent #3. The main problem is that Shields is 31 and under contract for just two more years, and Davis has only his 3 arbitration years left.
Meanwhile, the Rays get 6 years of both Odorizzi and Myers. Odorizzi is probably better than any pitcher currently in the Reds system and Myers is what Jay Bruce was to Reds fans when he was a prospect.
If the Royals were 2 starting pitchers away from being a World Series contender, this might make sense. I still think they'd be lucky to sneak into a Wild Card slot with their current roster. They've still got quite a few holes to plug.
