I don't like the 3 knockdown rule at all, because it takes away the ref's ability to do what he's paid to do, and that's make judgement calls.

The rule is designed to prevent a fighter from suffering unnecessary punishment, but isn't that what the ref is in the ring for? If you don't trust your ref to make the right calls, then why is he even out there?

All knockdowns are not created equal. For example, while Marquez's 3 knockdowns were all legit knockdowns on clean hard punches, he never seemed to lose his awareness or his senses. He just was surprised by Pacquiao's speed and power. He deserved the chance to keep fighting.
