I counted 4th PF, but whatever, Dirk is on the shelf for a while, and Harrison Barnes is out as well. I like Kostas chances for minutes now. But there is another shoe to drop. I don't know how that two way contract works but that also may come into play. Worst case he ends up in Dallas playing for the Frisco Legends--20 miles from the Mavs.
IMO if the 2018 draft was today, Kostas would be mid-2nd round.
