Past : Hogan - He was good, some will even say great but his star was a lot brighter than his talent deserved. This is done in comparison took how much he drew also. If he wasn't an icon he wouldn't be here, a victim of his own success to an extent.
Current : From an IWC standpoint Mark Henry. People carry on talking about how he can save the main event scene but I just don't see it, he's horrible in ring and incredibly injury prone. His angry gimmick was also dull to me, he's a decent talker but nothing special at all. I'd rather push Clay as a monster heel.
From a WWE standpoint Cena for the same reasons as Hulk.
