Emanuel Miller (born June 19th 2000) is on a two-way contract with the Austin Spurs of the NBA G League. While not active for the Spurs playoff run, he is still a part of the roster, which makes him a part of this Finals team.
Potential nightmare fuel for the Knicks should they find themselves in that predicament on June 19th, but they appear to have a handle of this series for now.
