#4 A lot of smoke and mirrors
There are no two ways about it—the collective members of DX and the nWo are well past their physical primes. Of the presumptive five core participants in this match, only Triple H could claim, with a straight face, that he’s near his best, and a part of why we probably won’t actually see this match is that at least Hulk Hogan and Scott Hall probably couldn’t get medically cleared to work a full blown match at this point.
If WWE were to make it happen, we can rest assured that there would be a lot of smoke and mirrors to mask the limitations of the performers involved. Not unlike Triple H’s match with The Undertaker at Super Show-Down, outside interference, plunder, and brawling that goes well outside the ring would probably all be a part of covering up for how much slower and less crisp everyone involved in this match would be, relative to their primes when they were some of the best workers in the world.
