Not formal til officially summer. After that, as of this year it is 2 hours per week of "official" practice time. From he article, one coach(I forget who) was planning on breaking it up into three 45 minute sessions per week as to not overload the team. Some coaches will use 2 hour sessions in their entirety at once. Either way, it is great for the team to get together early and learning the system and practicing. I don't know when Lavin and crew plans to start, but I'm guessing soon.
