5 Superstars who thrived in NXT but are struggling on the main roster

#2 Bo Dallas

Bo Dallas (right) took NXT by storm

Well, it was a tough one and he almost made the top spot, but Bo Dallas fits in at number two on the list.

He was once the longest reigning NXT Champion - only to be surpassed by Neville and Finn Balor - and even had an impressive main roster debut in the Royal Rumble where he lasted 20 minutes and eliminated the then Intercontinental Champion Wade Barrett, and then defeated him again in singles action the next night on RAW.

In fact, upon his official call-up to the main roster, Bo Dallas actually went on a rather impressive win streak where he even defeated Dolph Ziggler and The Great Khali.

However, it all went downhill for Dallas after he defeated Mark Henry three times in singles and tag team action. Well, immediately after that when Mark Henry effectively squashed Bo in a Hell In A Cell pre-show match. The former NXT Champion then had a four-month spell on the sidelines that effectively killed his singles push.

Bo's return saw him tell Sting to Bo-lieve to be greeted with a Scorpion Death Drop, and also interrupt Brock Lesnar to be decimated by The Beast Incarnate.

Things never quite picked up for Bo again as he became part of the Social Outcasts and more recently The Miztourage. While Dallas, like Curt Axel, is still a constant on television, it seems like any singles push is well and truly gone.
