That I honestly can't answer. In fact, this is the first I've heard of it.
I never worked or even spoke with anyone with ties to Luger. About the only insider scoop I have regarding him is from shoot interviews and books. Those are sketchy at best, but I've heard from more than a few different sources that Lex was originally slated to head the nWo in what ultimately became Hogan's spot.
Bischoff brought back the nWo idea from Japan, where another promotion was doing something similar. Bret was going to head up the faction with Hall & Nash, but decided to stay put in the Fed. So, the next choice was Luger. Hogan caught wind of the idea and used his pull to nab the spot to boost his then lukewarm career.
LUGER? Nash said on "WWE Legends", on a feature about the NWO, that the choices for the 3rd man to join him and Hall were either Sting or Hogan. Sting refused to do it; Hogan did initially but changed his mind later. As Nash put it,
"Thank God that Hogan has the business savvy to watch that money train leave and go, 'It's not moving that fast. I can still jump on it'."If it's still on YouTube, you should check it out. Nash said that his whole foray back to WCW started, thanks to Hall. To him, the
"stars were lined up perfectly" for WCW.
"What are the odds of Diesel and Razor Ramon being up 5 days after each other?"Hall wanted Nash to jump, because he knew Big D would be offered more money, being a former WWF champion (and having that belt for a year). Thanks to his "favored nations" deal, whatever WCW gave Nash, it had to match with Hall. And Hall was getting way more than what was known in WCW as "Sting Money" ($750,000/year, according to Big Daddy Cool).
To steal from one of the ribs on WCW, Billionaire Ted was actually getting some of those WWF New Generation superstars, two of the biggest ones actually.
As for WM X, I can easily believe the old man wanted to put the strap on Lex. The way they were pushing him, it was the only thing left to do. If Luger was dumb enough to leak the spoiler, then it's very possible that the double main-event was a swerve, which Vince was known for doing under such circumstances.
I've always stated that, had Hogan not returned, Bret Hart wouldn't have lost to Yokozuna at WM 9. I think the plan was to have Yoko beat Bret for the title at another 1993 PPV and have Luger win it at WrestleMania 10. Bret claims that Hogan didn't want to put him over, which is why he dropped the belt back to Yoko. If that's the case, that might have somewhat gummed up the works for Luger. Bret Hart may have felt he had to beat Yoko to legtimize himself as champion, sincce Hogan didn't job for him.
