WWE's Seth Rollins on Fighting Dean Ambrose, Their Summerslam Match, and What Daniel Bryan Taught Him About Life

If there's one life lesson we've gleamed from decades spent watching professional wrestling, its this: Your best friend could possibly turn into your worst enemy. As unthinkable as it may seem, we're willing to bet that you and your bestie could easily become frenemies (or worse), given the right set of circumstances.

It's something that happens quite often in the wrestling world, where close-knit allies (like, say, Hulk Hogan and "Macho Man" Randy Savage, who feuded both in wrestling rings and in real life) sometimes become hated enemies. Just ask WWE superstar Seth Rollins, as he's spent most of the summer battling his former storyline compatriot Dean Ambrose.
