FWIW, Kostas is putting up very pedestrian numbers in the G-League.
https://stats.gleague.nba.com/player/1628961/
Thru 12 games he's averaging 9.1 pts and 6.3 rbs and 2 blocks with a +/- of -2.
He's shooting 45% on FGs, 7.7% on 3s and 59% on FTs.
Considering that his parent team, the Dallas Mavs, are 12-10 and overachieving right now, it'll be interesting to see how they plan on using Kostas on the NBA roster. As a 2-way player he's allowed 45 days with the Mavs, but they won't bring him up unless there is playing time available as they are fighting for a playoff spot. The West of the NBA literally has 12 teams with legitimate opportunities to finish over .500 so every game counts, which may not work in Kostas' favor. Time will tell. So will his stats!
