Contending teams can never have too many relievers

The Kansas City Royals made it look all so easy in 2014. With their bullpen trio of Kelvin Herrera, Wade Davis and Greg Holland, the Royals were almost unbeatable when they had the lead in the seventh inning or later.

It's no surprise that a number of teams have sought to emulate that success. Even this past week, as the days and hours ticked down to the trade deadline, some contenders clearly felt one capable closer wasn't enough. The Washington Nationals added Jonathan Papelbon to a bullpen that already included Drew Storen. Joakim Soria was traded to Pirates, where he'll join Mark Melancon in the late innings.
