[HOUDINI]

I remember Mercante talking about that last round. He said he breaks rounds down into 3, 1 minute sections. In that 15th round Norton did nothing but follow Ali around at distance for the first 2 - 2.5 minutes while Ali was working, boxing, moving and jabbing. Norton was not being aggressive and with this not an effective aggressor. It was only the last 30 seconds or soo where Norton trapped Ali in a corner and pounded away. Since Ali won the first two minutes of that round and Norton did nothing spectacular in that last minute Mercante gave that last round to Ali.
