I can't really say much about the guy because it's only been within the past month or so that I've been able to keep up with NXT due to the WWE Network. He hasn't been featured all that much or talked about when compared to Neville, Zayn, Dallas, The Ascension and some others.
When I saw the vignette on Raw last night, my first impression was that Adam Rose struck me as a combination of Fandango and Russell Brand. He dresses very flamboyantly, all sorts of flashing lights like Fandango, looks like he live some hedonistic life, dresses strange like both guys do and there's the whole accent bit that puts me in mind of Brand. I already like him much more than Brand, who I think is an overrated talentless hack, but that's neither here nor there.
Based on those first impressions, I'm not expecting all that much out of Rose. He's spent most of his career wrestling in South Africa, he's not someone that has any sort of buzz or rep from the indy scene, he's been in WWE developmental since 2010, he turns 35 years old in late July and he doesn't strike me as someone that'll be taken seriously in the long run. I think he'll be a momentary and likeable curiosity like Zack Ryder and Brodus Clay.
