The Mysterio thing proves exactly my point. Mysterio was booked as a giant killer and a guy who used his speed,athleticism and heart to beat down the big guys. Had he been a lightweight or Crusierweight champ his entire career, would've been a harder sell but WWE never put any kind of label on him which in turn allowed him to reach the top.
Crusierweight division was awesome in WCW BUT u never realistically could've bought any of them taking the belt from Hogan or Goldberg thanks to that label. I remember when Rey beat Nash in WCW and thought it was the dumbest thing i had ever seen.
