The Simple Box is strategically very similar to the Box +1 d-zone coverage Our penalty kill set-ups closely mirror the characteristics of each of our defensive zone coverage systems. In this case, our Simple Box is very similar to the Box +1. It is great for covering the front of your net, but it is not very aggressive. So don't expect to get the puck back very quickly. This can be a great "starter pk" for youngsters or inexperienced players. However, you should quickly work toward implementing one of the more advanced penalty kill set-ups such as the Wedge +1 or Expanded Wedge +1. Enjoy!
