5 plays per team for the overtime seems strange. Why 5 and not 4 as they are starting at the 5 yard line?
The 5 plays all start from the 5. If the first play gains 3 yards it doesn't count for anything and the next one goes from the 5. I also assume the touchdowns aren't counted as touchdowns but rather just successful tries. So the final score would be something like team A wins 24-24 (3-2) meaning it was tied at 24 and they got 3 successful plays in overtime while the other team got just 2.
