My son plays for O2 box. He has played up north as well as some NLL junior programs. I can say after being at the practices and tournaments that the O2 coaches are constantly teaching and have a lot of fun with the boys. He plays on the 9/10th grade team and they have been in the finals of all three tournaments so far. We plan on moving over to their field program because we are so happy with the box program. If you want authentic box I highly recommend them. Authentic box isn’t for everyone though if you are just looking to do something in Winter I wouldn’t try to play for them it will be to difficult.
