The Chicago Cubs lost out on the one true everyday catcher available in free agency, Russell Martin, when he signed a five-year deal with the Toronto Blue Jays, which meant they'd either have to patch something together from part-time players or take the trade route to find a full-time option. Fortunately for them, the Arizona Diamondbacks happened to be having a clearance sale on everyday catchers. The D-backs traded Miguel Montero to the Cubs for two low-value prospects.

Montero was a star-caliber starter for several years, with three 3-WAR seasons or better in a four-year span, but his offensive production took a nosedive after 2012 and hasn't bounced back, in large part because he no longer murders fastballs like he did in his mid-20s.
