2. Scott Hall
WWE.comWho on Earth thought that, in 2002, the WWE should re-sign Scott Hall and thrust him into one of the most important storylines of recent years? Hall was publicly struggling away from wrestling, and he had a wealth of personal problems that really didn't justify him signing up with the WWE once again. If it had been anyone else, it's highly debatable they would have got the gig. But the WWE invested some faith in Hall, and brought him back as part of the nWo alongside Hulk (Hollywood) Hogan and Kevin Nash. They clearly trusted him to pull the role off, but their trust was very much misplaced. This was one such return that didn't just make Hall himself look bad - it made the WWE look pretty shocking, too. Hall was all over the place throughout many of his appearances on WWE TV, and he just didn't look right for the role all the way through his short run with the company. In some ways, you can't really blame the WWE for giving it a go. Had Hall been in decent shape, the nWo angle would have been absolutely phenomenal from start to finish, instead of limping along on several occasions without any real conviction. Eventually, Hall ended up being fired by WWE in May after the notorious Plane Ride from Hell incident - another victim of that iconic wrestling moment. He lasted just four months on the main roster, and proved to everyone that the WWE put plenty of faith where they simply didn't need to put it.
