9 players who gained the most in NBA summer leagues

The NBA's summer leagues aren't always good predictors for the future. But as things wind down in Las Vegas, USA TODAY Sports' Kofie Yeboah takes a look at nine players who are most likely to take July production into the regular season:

Cavaliers PF Anthony Bennett

While Andrew Wiggins has done well in Las Vegas, the previous year's No. 1 pick has been surprising people with his play, too. Maybe it's the low expectations after his forgettable rookie season. Bennett lost weight and has averaged 13.3 points and 7.8 rebounds a game in summer league. This new level of intensity shows Bennett is more motivated after showing up out of shape last year.

Pistons SG Kentavious Caldwell-Pope

The No. 8 pick in the 2013 draft was a pleasant surprise at the Orlando summer league. Averaging 24.0 points and 7.4 rebounds a game, Caldwell-Pope showed the Pistons that he can be a viable offensive option in the long run despite a rocky rookie year. In Orlando, KCP not only showed the ability to score on all three levels, but also showed improvements on defense and the boards.

Suns SF T.J. Warren

The No. 14 pick in June's draft has emerged as a top scorer in summer league, and he is doing it in an efficient manner. Shooting 59.6% from the field, Warren has used his offensive arsenal to stay one step ahead of the defense. Although the North Carolina State standout hasn't made a three-pointer so far, he has shown that he is able to score from the mid-range on in, using deceptiveness to make up for a lack in athleticism.

Bulls SG Tony Snell and SF Doug McDermott

The Bulls' first-round picks in 2013 (Snell) and 2014 (McDermott) formed summer league's most exciting wing duo. Snell is averaging 20.0 points a game, McDermott 18.0. While McDermott has been the more efficient of the two, both should be good role players who can space the floor. The Bulls no longer seem to have an deficiency of offensive options.

Jazz C Rudy Gobert

The 7-2 Frenchman should have Jazz fans excited. Gobert has done a great job defending both his man and the rim, areas of need for Utah. His field goal percentage is astronomical for a double-digit scorer. In addition to the perimeter promise of Exum, Hood and Burke, Gobert seems like he will be able to help the Jazz as they continue their rebuilding phase.

Rockets PG Nick Johnson

So far, the second-round pick has been more impressive than his former Arizona teammate, No. 4 overall pick Aaron Gordon. Johnson has used this summer to league to address the questions in his game, playing like a point guard. He had a triple-double against the Brooklyn Nets (15 points, 10 rebounds and 10 assists). With Jeremy Lin and Chandler Parsons gone, Johnson could use his athleticism to create a big role with the Rockets.

Heat SF James Ennis and C Justin Hamilton

Ennis isn't going to replace LeBron James, but he and Hamilton should have Heat fans excited. Ennis, a 6-7 forward and 2013 second-round pick, has shown consistency from the perimeter and from midrange. Hamilton, a 7-0 center who was on last season's roster but rarely played, has shown rebounding ability and can stretch out to three-point range.
