With the usual tryout camps, exhibition games, and other preseason activities being closed to the general public or otherwise inaccessible to the majority of the fans, we have compiled a list of all the players we know to be in training camp to start the 2020-2021 season. The list was compiled from line charts, Tweets, and secondhand accounts. This list is in no way meant to be a final roster and may be incomplete even at this time. This list will eventually be cut to a 25 player roster to start the season in November. We wish all the players the best of luck as they compete for a spot on the final roster.
