this has probably been mentioned already but in the lawsuit at least 2 of the 8 defendants were 1999 births. See at 0:43 of the clip linked below (clip only shows birth years of 5 out of 8):

There were only three '99s on the 2018 team...one of them was playing in Europe but one of the other ones is currently playing on an AHL contract (he is an NHL free agent) for the unaffiliated Chicago Wolves.
Is it possible that one of the leaves announced this week (maybe...most likely the one citing mental health) isn't one of the five and that maybe it's another player?
