In WCW, Diamond Dallas Page was a big deal. In WWE, he was not. That's just the way it was. Yes, his pop when he first showed up in WWE was pretty huge although they booked him terribly. He was the stalker of Undertaker's wife and it really didn't work well at all... wrong superstar for the role. His in-ring career in WWE lasted about one year. They did get it right by the end by booking him as a face with the ridiculous "it's a good thing" gimmick, but it wasn't the DDP that fans really came to know and love. He was in his mid-40s by then, so in WWE he was clearly past his prime compared to their relatively young roster at the time. If WCW was still around, he likely could have continued to wrestle because they loved featuring older talent and as one of Eric Bischoff's best friends he would have likely always had a job too. It's not like DDP is going to complain about his life, though. He's very successful with his DDP Yoga business and has helped guys like Jake Roberts & Scott Hall improve their life. However, he still suffered a bit when WCW died. No question about it. He went from a guy wrestling at the top of WCW to competing in basically a sympathy spot against Christian at WrestleMania 18 in a year.
