I am an avid hockey fan for more than 50 years. I prefer Junior and College hockey to pro hockey. I have a fairly good understanding to the complexities of Junior hockey throughout North America but I am still trying to learn the ins and outs of the different leagues and levels of College hockey. I am hoping that some of you can illuminate me. I see that some of the teams are starting to practice now? Whereas others such as ECAC teams seem to start at the end of August/ beginning of September. Is this by choice or do the different leagues have different rules? Is this governed by the conference or by the NCAA? I am hoping that someone can give a little summary. Thanks.
