#3. Worst - Dolph Ziggler
Dolph Ziggler was regarded as the most underrated performer in WWE. He enjoyed World Championship success in 2011 when he "defeated" Edge to win the title. He held the title for a couple of days before losing it back to Edge a week later on Smackdown. Ziggler's first reign was very short and not only did he win the title in controversial fashion, but he went on to lose his first title defense, that too cleanly.
This is by far one of the worst world title reigns in WWE. After winning the title for the second time, Ziggler suffered a concussion which took him out of action for a month and when he returned to have his first title defence against Alberto Del Rio, he lost the match and his title, ending his reign at just 69 days.
From that day on Dolph never went near the world championship gold. He has never successfully defended his titles on two occasions and he was still green during his two reigns.
