Seemingly there is a specialized clinic for almost every basic skill in hockey - skating, stick handling, shooting.... But what I have observed is the benefits of being able to play special teams post middle school hockey. Often these are the players who get the meaningful ice in high school. Why not a specific camp for special teams? 5-on-4 play, 5-on-3 play and limit it to 18-20 kids so you have two sets.
Problem is, most parents are stupid and would not see the value in this.
I think your spell check corrected that - think you meant to say most parents are stupid and don't know they should expect the team to work on these without needing to pay extra for a clinic.
