#2 Worst: Still no United States Champion
Here's one more champion that WWE forgot about. While they rewarded R-Truth with the US Championship after his years of service to the WWE Universe, they completely dropped the ball on him soon after by taking him completely off TV since. When this title could have been used to elevate someone like Andrade or Ricochet.
It is clear that his United States Championship run will be a very brief spell only. I wouldn't mind him losing to almost anyone at all in the roster, because seeing the Championship on TV would be better than having a namesake Champion. It felt like it was more relevant around Nakamura's shoulders, despite the poor booking.
WWE devalues its own champions and championships by letting the audiences forgot about the men and women that wield the gold during the show. Let's hope that he has a match at Fastlane.
