Roster sizes have increased to 17 players for the return of the season in Orlando, and the Philadelphia 76ers have signed 6’6” Australian wing Ryan Broekhoff for the remainder of the season. As the Sixers only had one player (Marial Shayok) on a two-way deal, they were able to sign one more player as a substitute for the second, unused two-way spot (providing they had three or fewer years of NBA experience).
No signings that take place right now are going to be game-changing. Players are primarily being signed to help teams round out their rosters and provide extra depth if others opt out of playing in Orlando or test positive for the coronavirus.
