Nico Harrison's ideas about Luka's value are correct

Luka had the perfect superteam around him in Dallas and couldn't get it done.

SGA, Tatum/Brown, Wemby, etc. carry less than ideal rosters and somehow manage to overachieve expectations.

Without PJ Washington and Kyrie Irving, we don't know if Luka can reliably perform in the postseason.

Draft scouts did say he lacks the athletic and defensive tools for the NBA, it's fair to assume they're right until proven otherwise.
