maybe. However, to answer your question about a fight between Xu ad Yi Long, Xu will absulutely lose to Yi Long in a stand up fight.  I am not impressed with his victories  over those fly chasing Kung Fu fighters that he fought in the past.  But Yi Long aint fly chasing Kung Fu though. He learned how to fight from Marital Arts university of China not from that useless traditional Shaolin things.  I truly believe Xu does not have what it takes to beat Yi Long. The only way he can beat Yi Long is if he can throw the upper cut or a head kick.  Yi Long is a tough son of a beast!  I am afraid that he will knock Xu out.
