#4 Eric Young
Eric Young was the one of the hardest working wrestlers in Impact Wrestling history, having gone through every possible gimmick imaginable before finally becoming a main event player and Impact World Heavyweight Champion.
EY left Impact in 2016 and signed with WWE that summer. He debuted on the brand as the leader of the faction, SAniTY.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
The group initially received a strong push which included feuding with other top tandems like the Undisputed Era, and becoming NXT Tag Team Champions. The group were drafted to SmackDown in 2018, but that was a move that left many fans wondering why it happened at all.
This was because it took over two months for the group to debut on SmackDown after being drafted, and then they made very sporadic appearances after. This would then turn into losing every match they had when they were used, so the decision to move the group to SmackDown was made with zero plans in store for them. One full year after the move to SmackDown, the group disbanded when they were split up in the first draft of 2019.
Eric Young found himself on RAW, but you won't find him on it very often. The only time EY is ever seen, is sometimes in pursuit of the 24/7 Championship. This late into his career, he only stands a really good chance of a resurrection if he returns to NXT, where they could put him to better use.
