Rpreoduce csv or delay iteration

Im trying to development a simulator of volleyball. Im read a .csv with what it has the information. I need reproduce the plays with the csv´s information, i need do a iteration with delay beacause the position of players and score in the table show me the last iteration of csv data that i read at the start of the simulation. what do you think about his? Read all csv at the init and reproduce or read line by line and reproduce the line??

Sorry by my explanation, if you have any question asking me.
