The Orlando Summer League is in full flow at the Amway Center in Florida, while the Utah edition tipped off yesterday at the Vivint Smart Home Arena as the next generation of NBA stars hone their talents alongside undrafted hopefuls looking to impress a franchise.
Here are four of Monday's biggest performances from the Sunshine State and Salt Lake City.
The Dallas Mavericks may have lost their second game in succession in Florida, but it did not stop former Marquette Golden Eagles player Vander Blue from showing his talents.
The undrafted product from 2013, who has been involved with the Boston Celtics and L.A. Lakers but spent most of his time in the D-League, posted 23 points as the Mavs fell 92-85.
During his 25 minutes on the hardwood, he showed a dead-eye from the field, shooting 7-13(53.8 percent), including 2-5 from three-point territory.
He also showed a composure from the free-throw line as he shot 77.8 percent on his nine attempts. Two steals also showed a willingness on defence.
Competing in his third Summer League for the Oklahoma City Thunder, Semaj Christon was able to impress once again as the Western Conference franchise lost to the Charlotte Hornets.
The 2014 second round draft pick was a D-League All-Star in 2015 and has spent his professional career with the Oklahoma City Blue and Italian franchise Consultinvest Pesaro. His latest impressive showing came as OKC suffered a 78-74 defeat to move on to a 2-1 record.
The guard struggled from the field as he shot just 4-15 and was 33.3 percent from behind the arc on his three attempts. However, his constant driving to the basket caused all sorts of problems for the Hornets as he picked up 14 points from 18 free-throw attempts.
He finished with 23 points and his six assists, as many rebounds and four steals showed the all-around play needed by a point guard.
The forward displayed the understanding of a player who has amassed over 100 appearances in the NBA and is competing in his third Summer League - picking up MVP awards in Vegas '15 - as he dominated for the San Antonio Spurs against the Boston Celtics in Utah.
The 2014 30th pick, who has played 111 games for the Spurs and started 19, finished with a plus/minus of 21 as San Antonio dismantled the Celtics 90-69.
He shot 62.5 percent from the field, nailing ten of his 16 attempts and was 2-3 from downtown. Shooting 3-4 from the free-throw line saw him finish the tie with a game-high 25 points.
Seven rebounds, four steals and three assists showed the maturity of a player who is looking to really stamp his mark on the big league next season.
During Ben Simmons' first game for the Philadelphia 76ers, the power forward was the player who impressed the most. While the Australian went off with a calf injury having played some neat basketball, Christian Wood's performance showed the benefits of returning to training early.
The undrafted player had just three weeks off before heading to the Sixers' training facility, and he shone as Philly lost 102-94 to the Boston Celtics.
His game-high 20 points came off 7-9 shooting from the field and a 50 percent success rate from behind the arc on his two attempts. He was also 5-7 from the charity stripe.
With five rebounds, Wood really looked to assert himself off the bench and will have another chance in game two as the 76ers plan to rest Simmons.
