Re: How did HBK have so much influence over Vince?
Shawn was the one who encouraged Vince to go the way of the Attitude Era if he wanted to compete with WCW. They were on the verge of going out of business. And, it obviously worked.
Also, if things weren't going good for a particular wrestler, back then, Vince liked it if that wrestler got in his face alittle bit and aired their grievances with Vince to his face, rather than just go behind his back and bitch about it. Shawn did that, too. Shawn also went to Vince with some of his ideas, which guys like Bret never did. Overcoming WCW, Shawn made part of his mission, too. Some of the other guys didn't care that much, as long as they were making their money. Shawn was a prick, but he cared, and wanted the WWF to make it and beat WCW, which they did.
