Different players but both like to pass.
Naar did well at college and is a good, composed point guard who can find the open player and, more recently, shown he can score himself. Maybe he's not the most athletic PG in the comp but he is smart and athletic enough. Maybe if he had the higher level of athleticism, he would've followed his college alumni into the NBA (you know, the ones he overtook on college assists record)
Lamelo is very composed for an 18-year-old, can create for himself, and looks for his team=mates. In fact, if some of them were catching and finishing the passes Lamelo gave, his assist stats would look even better (an extra 3 a game give him a double-double average). And stat padding? While his shooting percentage could be better, he does well in both assists and rebounds, and has pretty low T/O for someone who has the ball in his hands so much (on par with Casper and Bryce).
So, both are good players and I'm happy they are on the Hawks roster
