Having seen only youtube video of it, and reading that he had 1.8 seconds to do it, I don't understand how he had enough time to catch, dribble, get stripped, get the ball back & shoot in under 1.8 seconds. Did the Nets get some home-clock-operator advantage?
Looking at the video on ESPN, it looks like the clock didn't immediately start when the ball hit Harris's hand on the inbound, meaning he got an extra .1 or .2 to work with. But, hey, if the 76ers make their FT's (they missed 14), then they don't need to worry about .1 or .2 seconds.
