Are you dense enough to think that DA did not tell them to warm up? That's why there is a portion of practice and pre game dedicated to warm up
Do you also not think that the strength and conditioning coaches are not telling them these things
I like Rizzi but he's doing a lot of things just for shake-up effect. To try and make them do things differently. Believe me just because warm-ups were not voluntary does not mean that players were just standing around and not stretching. Soft tissue injuries around the league are up, must be because HC's are not making warm-ups mandatory
