Kittle, Kelce, Olsen and Co wanted to put something together to form a sort of fraternity or brotherhood at the position
where they come together, do workshops, share what they do in training, prep, life, etc, to be better at the position and stay balanced personally.
I believe it is by invitation only, but what that means to me is that they all invite all guys on active rosters and maybe a few others. They had 50 turn out last year.
