#4 Drew McIntyre

Okay, I'll freely admit that this entry is cheating a little bit as we all remember Drew McIntyre as 'The Chosen One' and then as part of 3MB. Both spells in which the Scottish wrestler clearly lost matches.
However, McIntyre then left the WWE and honed his craft and skills on the independent wrestling circuit, becoming a better wrestler in the process. He's now returned to the WWE as a different performer, so I think treating the two WWE runs of Drew McIntyre as different is a fair thing to do.
Which brings us to his second run in the WWE, where he's the current NXT Champion. McIntyre returned on May 20th, defeating Wesley Blake, and has remained unbeaten ever since, beating Bobby Roode, the previous unbeaten Killian Dain, and Roderick Strong.
