15 worst New York Yankees free agent signings in franchise history

13. Brian McCann: Five Years, $85 Million, Only Three Years Completed, 2013-14 Offseason

McCann appears on this list over Burnett because of what he failed to deliver: postseason success of any kind. Forget about World Series glory. McCann, a member of the four-man spending class of 2013-14, played one postseason game in his Yankees career, regressing annually along the way.

He also served as the commissioner of the No Fun Fantasy League, presumably doling out points for referees making the right call and cops diligently patrolling security.

After establishing himself hands down as the greatest catcher in the National League from 2006-2013, making seven All-Star teams in eight years, McCann was immediately ... drumroll, please ... not that guy anymore as soon as the Yankees paid him!

He hit 23, 26 and 20 homers during his age-30-through-32 seasons in pinstripes (fine), playing like a 36-year-old every step of the way (bad). His batting averages in the Bronx were .232, .232, and .242, and his OPS+ marks were 94, 105 and 99. The Yankees paid for a dogged captain-type with an electric bat and received Matt Nokes.

Importantly, he was traded to the Houston Astros prior to Year 4 of his deal, stole signs, and essentially eliminated the Yankees with a two-out, two-run double to put the 'Stros up 4-0 in Game 7 of the ALCS. He also, crucially, called for those 24 straight f****n' Lance McCullers curveballs. No freaking thank you to Brian McCann.
