Gilbert Melendez is ranked #1 at LW, Jacare is ranked #5 at MW, and Saffedine is ranked #8 at WW. Who of these guys has beaten anyone in the top ten in UFC? None of them but no one questions their ranking. It's all based on their fights outside of UFC.
However, none of Tex's wins outside of the UFC were noteworthy either. At least Jacare and Gil have some impressive wins outside.
