For Paul to claim to be a legitimate boxer, those first 4-5 rounds were an embarrassment. From the opening bell, he ran scared. And when ever Joshua cut off the ring and cornered him, Paul just hit the mat and tried to tackle him. The ref finally had enough and called time, and you could hear him say to knock the bullshit off, this isn't what the people paid to see. After that, Paul stopped running so much and Paul caught him and repeatedly knocked him down until he finally caught that big right hand to end it.
Expect to see Paul fight a few creampuffs to get back on his "win streak". Doubtful he steps into the ring again with another legitimate fighter.
