I think that with facts that you wrote its completely opposite.
The fact that promising fighter lost to less known fighters has more potential to find a real talent. The must have something in them if they won these fights.
That so called "less known fighters" already got their ass beat by mediocore fighters, and now theyre beating the best talent of tuf. I think its the other way around, guys like Jimmie Rivera, Louis Gaudinot and Akira are just not what they were hyped to be. The only fighter with potential is Diego Brandao, and even he didnt have his first fight in the house...
Its ironic you post in this thread after last night, when the self-proclaimed "future world champion" Akira Corassani got tapped by Dustin Neace
