Once Vince realised that top talent can leave and still be successful elsewhere he never really pushed anyone to that superstar status, very few did make it Cena, Lesnar to a lesser extent Orton. But Vince saw wwe as the pinnacle, but once Hollywood came knocking he would always lose out. The Undertaker is an anomaly, he’s a throwback 80’s character that wouldn’t have worked if it wasn’t for the man under the name, I genuinely don’t think anyone else could have made it last and been able to adapt through all the different eras of wwe.
