If I remember right, the bell rang about a split second before he was floored. But if the bell hadn't rung, it should've been scored a KD IMO.
Tua himself was still throwing punches. It was a legit knockdown otherwise but due to it being after the bell, it shouldn't be counted, much like Starling-Molinares. http://www.youtube.com/watch?v=lVzoSKgmr1A
No wonder he went down. His feet were totally square on and in a straight line. Hagler and LaMotta would both have went down in the exact same situation.
Sure was. Rahman had ridiculous power. Compare the shots he took from Shannon Briggs, Vitali Klitschko, Frank Bruno and others to the right hand that put him down like he had been shot from Rahman. Marion Wilson actually said Rahman or Shannon Briggs were the hardest hitters he ever faced.
This is different to the shot Rahman took from Tua after the bell where he was really hurt, Tua doesn't look hurt and its true his feet are together so no wonder he went down, looks like they evened up and any knockdown after the bell doesn't count in my book.
