Sure, he looked impressive at the 2011 Royal Rumble. Long, black hair (even if it was washed into his graying scalp), still a physical specimen for a man at his age, and in short spurts, can be effective. These are things we didn't get from him in his last run with TNA.
There, Kevin Nash looked old and slow. He seemed to not really want to be there other than to cash a check or to run the company. Maybe that's because the makeup of TNA is far different from WWE.
TNA mirrors the WCW locker room, Big Sexy walked into circa the early 1990s. A company on the rise, but not exactly sure how to get over the hump. Nash was able to lend his name and considerable wrestling abilities to help WCW get there.
That unfortunately didn't translate as well as TNA.
But even before that, Nash turned up lame during a WWE match when the new-look nWo was formed. A big boot ripped up his leg and effectively ended the nWo's flailing run in WWE.
That's not how a guy as good as Nash wants to be remembered.
He doesn't want to retire from the perceived minor leagues that TNA is known as and he refuses to leave the WWE canvas for good looking anything less than dominant.
Even he said it via Twitter not long after he left TNA: "I'm back in the WWE family and I'm never leaving again."
He knows his legacy is ultimately only as good as WWE allows it be.
So it makes sense that as his fellow clique-mate, Triple H, is gaining power both on- and off-screen in the "E," that Nash get a little benefit from that. He's signed to a Legends deal that pays him well and gives him flexibility to ply his craft in other places, but he ultimately wants to end it all in the middle of the WWE's squared circle.
He'd hosted WWE parties for previous PPVs this year and no one though anything of it. He also tweeted Punk recently saying he'd like to be his enforcer. Again, no one thought anything of it. But it looks like it might have been planting the seeds for one final run for the man the call "Diesel."
Nash can still go, if albeit, slower and with the aid of someone who can make him look better than he is right now. But this move makes him relevant to WWE and its fans one more time. It gives him a chance to go out the way he feels he's entitled to.
Now what exactly happens here remains to be seen, but I think Nash will be in the forefront of WWE programming for the near future and it will do wonders for reviving his career and for the WWE product.
