Supposedly Crowe appears in an Adam Rose vignette as a DJ. Kalisto is also there doing a light show. Hopefully those were just one-offs as it'd be a shame to see them saddled with a comedy act especially since the Crowe gimmick looked like it could have been interesting. We'll see.
Adam Rose debuted later on in the tapings, btw. So I'd guess that's the end of the Leo Kruger character unless they have him working both gimmicks and expect the NXT crowd to NOT exploit it. Can't imagine the guy feels too good, been in development nearly 4 full years, closing in on 35 years of age, seemed primed to make his main roster debut with a cool gimmick. And instead they saddle him with a comedy gimmick. Guess it'll help him get to the main roster and fit right in with most of the undercard comedy guys, but Kruger actually had potential to be in some meaningful programs.
