You can rest assured that if his opponent goes past the 7th round, Juanma is gonna be in deep **** for the rest of the fight. Is it possible that it's impossible for him to develop good stamina??
It wasn't his stamina that was the problem it was the endless number of punches bouncing off his head.
Truth is JuanMa is a 6-7 round fighter. After that, he gets sloppier than **** and breathing like he is dying.
