10 WWE Stars' Best Non-WWE Matches

10. Adam Cole (Vs. Kyle O'Reilly, ROH, 2015)

Fans who followed Adam Cole's turn on the independent circuit breathed a sigh of relief when he turned up on NXT alongside his former running mate Kyle O'Reilly.

First, because it ensures - as the head of a faction - he won't be lost in the shuffle, and second because it reunites him with the man he did much of his best work with in ROH.

Their best match came at December's Final Battle in 2015, where on night one Cole defeated his one-time tag team partner in a bout whose only flaw was that it was just five or ten minutes short of being a genuine, for-the-ages Ring of Honor classic.

If this is what Cole could do at the age of 26, though, we're probably going to have a lot of fun watching him over his time in NXT and beyond, during which time he's widely tipped to become one of the very best in the world.
