That's insane. It's almost 2 full seasons worth of relief pitching. He's like the Daniel Murphy of post season pitching.
No it's not, Rivera was consistently good reg season and post season his whole career. Murphy is comparable to Beltran (hit like crazy in playoffs right before he was a free agent).
Rivera blew 2 series.
Which is why it is hard to label best ever. As good as he was, MadBum never blew a series!
