Management pushed him as a main eventer with WWE angles like the Vickie/Maria stuff and smart fans hated him for it
For a brief period there was a general consensus between management and the fans that when he had MITB and cashed it on Del Rio he was dimes until he got fucking concussed
After that management never saw him as a main eventer again which gave him angles people actually liked to let him get over, barring his miraculous run at Survivor Series 2014 which should have been a main event relaunching point if Da Beeg Dawg didn't happen, which made him a smart fan darling
tldr it was everyone's fault except his but at different periods of time
