If I was a coach, (oh wait I am) I wouldn’t want all of the cameras and stuff around. It can be distracting for other players and I would wonder if his mind isn’t always focused on the task at hand and more worried about his videos.
And on the goalie coaching front which is more of what I would do; I want to coach who is paying me, call me selfish but I’m not paid to put free goaltending tips out there for anyone and everyone. If thats how I make a living everyone can pay for my expertise.
