Why is all American fighters so hyped without no balls? Always just talking! Why?

Everytime they fight a ranked European they are destoryed but in America they are great as long as they fight American bums - just look at Lacy. He was a star in America but barely a top 25 in Europe. Look at Mack, the same pattern with a nice resume but the first time he faced an European beater he was KOed out cooled.
