#4 Eric Angle-Kurt Angle
Kurt Angle is regarded as one of the greatest wrestlers to ever step foot in a pro wrestling ring. But his brother Eric wasn't that gifted in the squared circle. Eric Angle was roped in by WWE in 2000, to help his brother Kurt in his feud with The Undertaker.
He was then signed by WWE on a developmental contract to better his in-ring ability. But, Eric Angle's matches in WWE were restricted just to OVW, the developmental territory that he was sent to by WWE.

This meant that Eric and Kurt could never team up together in a WWE ring. The former had just a handful of matches in OVW, before being released by WWE in 2003. Eric tried his hand at independent wrestling, but he had just a few matches there as well before retiring.
Eric, though, played a key part in his brother's feud with Brock Lesnar for the WWE Championship, helping Kurt keep the belt during his feud with The Beast.
