Edge on The Undertaker's Streak
"I know this sounds crazy, but I felt I didn't need it because, by that point, I was already established," Edge explained.
"I was already a made man, and why give an already made man that feather in the cap? Brock Lesnar didn't need it. He's already made. Put that huge, neon-flashing sign, 'I ended Undertaker's Streak', on a new player that you know is gonna be one of your workhorses and take your company to the next generation.
To me, it shouldn't have ended until his final match. I said for years, let it be Roman Reigns, and at the end of the day, that will be the true passing of the torch. Well, it didn't end up that way" - he added. Edge had been tasked with putting up an amazing show at Backlash.
His match against Randy Orton at WrestleMania 36 was great, but it only put more pressure on the superstars to top their previous performance. Throughout the buildup to Backlash, the match was constantly hyped as ‘The Greatest Wrestling Match Ever’.
Edge will be back as soon as he can, and odds are he isn’t finished with Randy Orton. Those two seem to be in a war of words. Other legends are going to likely play victim to RKO until Edge’s return. He was really was injured during the Greatest Wrestling Match Ever. Actually, he was injured while doing “re-shoots” following the initial match.
