There has long been discussion about fighters that should be fighting in the UFC , but, for one reason or another, weren’t. Over the years that list has dwindled, as the purchase of MMA promotions Strikeforce and Pride FC (among others) by the UFC brought many of those fighters into the fold. Fighters like Shogun Rua, Wanderlei Silva , Rampage Jackson, and the Nogueira brothers all made their way from Japan to the inside of the world famous Octagon.
