I do not know the answer, but does anyone know what season Miami had its highest number of players in the NHL and what is that highest number? How many former Miami players are in the NHL currently? If there is a site I can find this information, please provide the referral.
You can do your own research on hockeydb. I would guess around 2016 for the high water mark. The actual single day “record” might be a total crapshoot as a lot of guys were in the league for very short amounts of time.
