I was never that big of a fan of his, but you can't deny his contributions and his credit in helping make the inaugural Wrestlemania a big deal should never be downplayed. Yeah, Hogan was already the biggest wrestling star in the world and shattering records, but if you read the book Sex, Lies, and Headlocks, they point out how even after Hogan was announced on the card, the majority of the tickets were still not sold until they actually jump-started the feud between him and Piper (which all began with Piper drawing mega heel heat by harassing Cyndi Lauper, who was a very popular pop star at the time.)
RIP.
