A lot of good times growing up watching 80s WWF.
A lot of debate over the years if the WWF would have got as big with someone else as the main star. They probably still would have been big enough to close off the territories. But it may have taken longer to find a big star. It was hard enough replacing Hulk Hogan.
Hulk Hogan with his larger than life physique and personality was the perfect guy for them to launch their expansion.
Even after his drawing power wasn't great in the 90s with WCW as people got sick of the red and yellow babyface. He manged to turn himself around to one of the biggest heels in the business.
