We have been spoiled, but Greg Holland 2013-2014 is the best a closer has been in this franchise's history.
Rios, Cueto, Infante, you can argue any of the guys who have struggled in 2015 haven't earned the leash they've been given, Greg has. Greg earned the 2nd, 3rd, 4th chance because he has been so good. Greg Holland was better than Soria, Monty, Quiz, Roberto Hernandez, any of them.
When it goes, sometimes it goes fast. Greg Holland is now an ordianry releiver, and he'll never be a valuable part of this team again. JMHO.
