I found this book to be an honest look at the world of hockey goaltending from mites to the pros. My son, who is a youth hockey goalie, enjoyed reading Robb's history and hockey philosophy. A good book for all hockey goalie parents, especially those who are new to the goalie world.
Positive

Over the winter, i seem to gain alot of weight. As a high school quarterback, that is not acceptable. Last summer, i think i went from 160 to 150. That's my gross weight loss. I'm not even talking about how much fat i lost. I gained a good amount of muscle over the summer, so i probably lost over 15 lbs of fat. I got my six pack back, and life was great. After the season, i just quit, and now my six pack is back in the fridge. I'll probably order some up next week and start again. These are great, and the results are amazing.
Positive

While this book is very good on providing scripture quotations, the commentary is dated and extremely biased. If this book were to be shared with people of non-Mormon faiths, they would become very defensive and rightly so. The author's invective toward the Catholic faith is appaling. Many Mission Presidents do not recommend this book. It could be dangerous in the hands of the untrained.

Negative
