jIM- this might confuse you, or help you now, or in the future

K-LO!!!!
In your opinion, under most rule sets, can you have two different players in the same exact pose, number and name, who run lets say, the sweep left and the other, sweep right? this would confuse the opponent coach (atleast initially) into wondering how this "individual" can run sweeps to both sides.
ESPECIALLY IF HE IS ON A ROOKIE BASE.
