10 Current NXT Stars Who Will Struggle On WWE's Main Roster

Recent WON reports have claimed that Lars Sullivan has been inexplicably absent from NXT's Orlando Performance Centre for the past month, fuelling speculation that he's either picked up a long-term injury, or worse, got on the wrong side of someone in the back.

At the moment that's all speculation. What we do know is that Sullivan is a serious unit - one whose neck is probably about the same size as Lio Rush's torso - and is therefore absolutely, definitely going to be one of Vince McMahon's favourites when he steps up to Raw or SmackDown.

Or is he? The truth is that, for all the claims that the WWE chairman loves a big guy, there's no end to the list of giant rookies who jumped up to the main roster only to be sent packing within a year or two: Snitsky, Nathan Jones, Heidenreich, Vladimir Kozlov.

You can easily envisage the 29-year-old following the same path, particularly since his own massive man credentials pale by comparison to those of fellow behemoth Braun Strowman, who has been dominating Monday Night Raw almost completely unchallenged over the last 18 months.
