Where has Kevin Nash been? ...I know he "got his ass handed to him" by HHH in their last match, but I think WWE really missed the boat with the whole "text message" storyline that Nash was involved in. I know that's off-topic, but I'd love to see Nash back in the future (in an in-ring, or non-wrestling capacity). Even if he's not nearly as good as he once was (some would even argue that he wasn't ever that great; even in his prime).
To take it even further (and I've talked about this in other threads, when Nash first arrived back in the WWE in 2011), I would have loved to have seen a HHH heel-turn with Nash by his side. Hell, I would love to see Scott Hall back as well. The three of them could be similar to the old-school "Corporation": with HHH playing the Vince role, and The Outsiders being this generation's Brisco & Patterson.
Any combination of original "Kliq" guys could work (ie: Shawn Michaels, X-Pac, Scott Hall, Kevin Nash -- I'd even include Billy Gunn & Road Dogg, were they considered part of the Kliq? ...or just lumped in because of the DX Army?), but I wouldn't want to see ALL of them running things. Any combination of three or four of them would work well, if the storyline was done correctly.
Seeing Nash walk out to the old nWo music was nostalgic enough to get my blood boiling for the past, it would be great to see them come out to DX music as well...seeing them walk to the ring wearing nice suits, and "running the show" would be fantastic (for aesthetic purposes only, I wouldn't want them doing ALL the booking, or with "real" creative control either). They would HAVE to be heels, at least that would work a billion times better than if they tried to be faces (like HHH currently is).
Obviously that's not going to happen any time in the immediate future, but I'd still like to see Nash return to the ring for a few matches a year at the least. Nash was always one of my favorites, and it seems he still has a bit of gas in the tank. Also, I've seen Nash mention how much desire he has to get back in the ring (via social media). Why is the WWE keeping him away?
Another guy I'd like to see back is Raven. As much as I'd love to see Raven back in the ring, I know he doesn't "have it" like he used to...not that he's really "bad" now, just older...but I think that Raven would make a great manager for a young high-flier. IMHO, Raven would be instrumental to help a young guy get over with a "dark" character, and create a character similar to how Jeff Hardy's was 5/10 years ago. It would be great to see someone like Justin Gabriel grow his hair long, get different ring-attire and have Raven as his manager. Just my opinion, but I think that combination would be great.
Goldberg would be great as well, but I don't think his heart's in wrestling anymore. Too bad, that guy was just phenomenal in the late 90s. Besides, Goldberg never really had the best attitude for the wrestling business. If somehow he was able to put his ego aside, then his return could be epic. Then again, it might have been Goldberg's ego that made him so great in the ring in the first place....
