why didnt melvin punch him back ?
Don't know.
Story goes that Melvin's girl was getting hit on by Titus, Craig wanted to have a 3some with her and Kelly. Melvin didn't like what he heard and confronted Titus about it in the middle of Golds.
Whatever was said, a few people broke the two of them apart. Then as Melvin turned his back Craig hauled off and hit him. Then the crowd broke it up again and they were separated.
Craig says he felt threatened. Melvin said his back was turned. How would Craig be threatened if Melvin's back is turned?
Figure it out on your own. Titus was usually all talk. And when he stepped up to the plate, he was usually blindsiding somebody.
