I followed Bader before the Ultimate Fighter and he was one of the more hyped fighters entering the show. Even in his prime though in UFC he didn’t have much value. He was a guy that would look amazing and tiers above against some talent(mid level, borderline contenders, over the hill fighters, except for Tito LOL) and just completely choke against elite fighters at the time(Rumble, Glover, Machida).
Even during some his dominant wins he was just boring and frustrating to watch as he would just sometimes lay and prey even though you knew he could smash them and finish easily but he just wanted to play it safe.
He also didn’t have much of a personality to market. DC really tried and help to WWE style his way in a match with him and it was just awkward and nobody cared still so it didn’t happen.
