This. IIRC, the 2012 didn't have to overcome a lot of adversity. They just won.
The 2014 team had to overcome a crap ton of injuries.
Which is weird, because I felt in 2012 like they were limping into the postseason, even though they had an awesome record. I remember being nervous about the whole thing. This year I feel like they're charging into October with a full head of steam, and today really cemented that.
