The NBA's Summer League is well underway. Some players have impressed. Nobody could argue against their strong performances. Their teams are excited.

Others have struggled. That's not the end of the world - this is the very beginning of these players' careers - but it's something to keep an eye on. Ideally, future NBA stars will be excelling at this level, but some are still developing their skills.

Finally, some players have just been a bit confusing. Take the Atlanta Hawks' Kingston Flemings. He's struggled in some areas, and thrived in others.

According to ESPN's Zach Kram, he's been the 9th-best rookie in Summer League play.

Let's start with the positives: Flemings has been remarkable on the defensive end of the floor. Kram was quick to give him that credit.

"Flemings was the best defender among the lottery guards in Vegas, able to stick with opposing guards and hold his own when switched onto opposing bigs," Kram wore.

That was a major selling point on Flemings as a prospect, and he's made good on his potential. His aggressiveness, active hands and strong instincts have helped him succeed on defense.

He's also been successful as a playmaker. Flemings is averaging 6.5 assists per game in Las Vegas Summer League play. Sure, he's also averaging 3.5 turnovers per game. That''s not ideal, but at this stage in a player's career, it's nice to even see Flemings' passing ability on display.

That said, scoring the ball has been a touch more difficult for the rookie floor general.

Flemings is shooting 33.0% from the floor in Vegas. It's the same percentage he's shooting from deep - which would be fine, only with such poor two-point efficiency, it's not strong enough to carry Flemings' efficiency. At the moment, it's unclear how Flemings will score the ball at the NBA level.

Is it time to be concerned?

No.

It may take Flemings a couple of seasons to score consistently in the NBA. That's fine. Most rookies struggle in one area or another.

It's encouraging that Flemings looks to have some league-ready skills already. He'll be a positive defensive guard from day one, and his ability to run the offense will be helpful.

If the Hawks were envisioning him as a franchise player, perhaps there'd be cause for concern. As more of a complimentary player, there's no reason to panic.

Yes, they'll want him to improve. Even if Flemings always struggles around the rim, a more reliable three-point stroke would go a long way. Coupled with his defense and passing, that would make him a strong NBA player.

Soon, Hawks fans will get to see him on the main roster.
