Didn't Ali call Perez a '****' ?
Ali accused Perez of being paid by gamblers to save Joe from getting KO'd early.
I think Ali did what he needed to do to win, but the fight was close.
Sure, the referee could have warned him, deducted points, possibly DQ'd him because the 'neck -hold' was getting ridiculous.
I'm not sure how much Eddie Futch protested at the time. Futch was a great cornerman but seemed a very gentle man. If it was Angelo Dundee in Joe's corner you would have heard him cursing Perez in his face and that might have made an impact.
I'm not sure of this, I don't know. Just speculating.
It doesn't allow SPlC but I think that's what Ali called him.
