#2 Maven
Maven won the first Tough Enough in 2002 and WWE saw fit to give the inexperienced newcomer a huge push. He eliminated The Undertaker from the 2002 Royal Rumble, although he was helped by a distraction from Lita, it's an honor reserved for top stars in the WWE.
Despite the early push and winning the Pro Wrestling Illustrated Rookie of the year award, things didn't work out for Maven. He was released in 2005 and later left wrestling to work as a bouncer after a failed stint in TNA.

#1 Lex Luger
After Hulk Hogan left the WWE in the early 90s, Vince McMahon saw Lex Luger as the perfect replacement for him but this was a role Luger wasn't ready for despite doing his best. For one, Luger had been playing the heel character 'The Narcissist' a few short weeks before his sudden push. In the end, he only beat Yokozuna by DQ in what was supposed to be his crowning moment at SummerSlam 1992, meaning he didn't even get a run with the title.
