2017 NHL ASG. I went to a red carpet kindof thing for kids before the athlete media sessions. Player after player signed a couple autographs or did a fly by (McDavid, MacKinnon, Ovechkin, etc). Crosby to his defense did say to his pr person that he was upset they didnt tell him to come down sooner so he could sign for all the kids.
Bergeron, Rask, and Marchand stopped for every single kid and every single picture.
The NHL rep who was with us told us stories of how amazing Bruins players are with anything for the league or charity and some specifics of players who suck (Karlsson was the one vivid story I remember).
