The first thing you must do for your NCAA Basketball Tournament box pool is to create the boxes. This is done by drawing lines until you have 10 rows going across and 10 rows going down, for a total of 100 boxes. When you are finished, your pool should resemble the one above.
Be sure to label one team at the top of the boxes and the other team going diagonal down the left-hand side of the grid. This is so potential players know which team will correspond to each number that will be drawn. If the teams are still unknown when you create the pool, you can always identify them by bracket region, such as East/West and South/Midwest. That way everybody will know which team will go be placed where on the pool.
Make sure to leave enough room for signatures.
