I agree, 2006 had the rise of RVD, Edge and the return of ECW. It all looked rosey. As for 2007, the Great Khali, Chris Benoit, Donald Trump its hard to specify what went wrong.
2006: Young and really
charismatic newcomers like Carlito, Mr.Kennedy, CM Punk and MVP. Legit uppercarder/main eventer talent like Edge, Jeff Hardy, John Cena, Rey Mysterio and Orton were still very young, and a great crop of stars headed by the enshrined veterans Shawn Michaels, Undertaker and Triple H. Also Batista, Booker, RVD, Kurt Angle, Kane, Finlay, Regal, Matt Hardy...
You cannot compare. Now there are people that think McGillicutty and Kofi are amazing. That says a lot about how standards have dropped.
