Five years ago, things were very different for Ronda Rousey and CM Punk. Rousey had been brought over to the UFC from Strikeforce, and became a UFC champion when she beat Liz Carmouche. Punk was coming to the end of a 434-day run with the WWE championship. They were at the top of their chosen professions.
Fast forward to today. Rousey left the UFC after two straight one-sided losses, and is currently starting a new career in the WWE. Punk, after walking out of the pro wrestling organization in 2014, is a fledgling MMA fighter with an 0-1 record and a bout scheduled for June.
