20 Dream WWE Matches That Only Happened ONCE!
8. Rob Van Dam vs. Rey Mysterio
When: 7 June 2006 WWE vs. ECW Head To Head
Do you recall WWE's 'Head To Head' show between the main brands and their own version of ECW? Most won't, which might make revisiting Rey Mysterio vs. Rob Van Dam quite the treat. For reference, this was the same episode that had John Cena warring with Sabu and Edge facing Tommy Dreamer.
Rey vs. RVD was better than both despite them being babyfaces who also worked extensively as tag-team partners. That union is perhaps why Mysterio and Van Dam only have this match to look back on as opponents. WWE seemingly weren't keen to make a habit of it.
PPVs of the era missed out big time.
