Trail..."splitting the court"

[cardinalfan]

I have seen several college games where the T "split the floor". I've also worked with guys who call college games that use the mechanic in high school.
I recently decided during the second half of a blowout game to try to "split" myself. About the third time down the floor, A1 made a long skip pass to A2, who started a dribble down the sideline.
Coach B jumped up and yelled, "He stepped on the line". I know the dribbler was close, but from my position I couldn't see if he actually was out of bounds.
At other times, I felt like the umpire in a football game. I had the constant fear of a steal and transition that left me in the way.
I didn't see the advantage, and I personally like the mechanic zebraman described better.
