Summer League Standouts: John Hollinger's Top Rookies from Las Vegas
The NBA Summer League has come to a close, and with it, players have showcased their talents on the biggest stage outside the regular season. Renowned NBA analyst John Hollinger has put together his list of standout rookies from this year's Summer League in Las Vegas, highlighting their performances and potential impacts for their respective teams.
Cooper Flagg - Dallas Mavericks
Despite a rocky start where he shot 5 for 21 in his first game, Cooper Flagg of the Dallas Mavericks has made a significant impression. Hollinger emphasizes that shooting percentages in Summer League can often be misleading, particularly in evaluating a player’s true skill set. Flagg demonstrated exceptional court awareness, driving to the basket with confidence and showcasing his ability to handle the ball as a point guard. His dunks and overall offensive play solidified his status as the top rookie of the tournament in Las Vegas, and many are excited to see how he will contribute to the Mavericks this upcoming season.
V.J. Edgecomb - Philadelphia 76ers
Playing in only two games during the Summer League, V.J. Edgecomb made an impact in limited minutes. His solitary game in Las Vegas against the Washington Wizards might not have showcased the best shooting performance—hitting only 4 of 14 attempts—but he still managed noteworthy stats. Over the course of 60 minutes, Edgecomb tallied 15 rebounds, 8 assists, 4 steals, and 3 blocks. Although his shooting accuracy will ultimately determine his role on the team, his athleticism and explosiveness suggest he will be a valuable asset for the Philadelphia 76ers moving forward.
Nick Clifford - Sacramento Kings
Drafted 24th overall, Nick Clifford participated in all six Summer League matches and stood out for his reliable and useful play. He successfully converted 11 of 24 three-point attempts, which may possibly have been influenced by luck, but his contributions went beyond shooting. Clifford showed strong defensive capabilities, consistently contributing on the boards and dishing out a total of 25 assists across the six games. His performance indicates that he may be poised to become an integral role player for the Kings in their quest for success in the upcoming season.
Brooks Barnhizer - Oklahoma City Thunder
Considered the best second-round pick of the Summer League, Brooks Barnhizer showcased an impressive level of activity throughout his eight games. While there are questions about his shooting, which will ultimately determine his ceiling, his performance demonstrated an ability to contribute defensively, recording an impressive combination of 27 steals and blocks. As the 44th overall pick, Barnhizer's tenacity and hustle may have earned him a look as a promising bench option for the Thunder.
Kon Knippel - Charlotte Hornets
A world champion, Kon Knippel began his Summer League experience slowly, hitting only 1 of 8 shots in a game against the Utah Jazz. However, he rallied to lead the Hornets to their first Summer League championship, scoring 21 points in the final match. Interestingly, half of his shot attempts were two-pointers, showcasing his versatility and suggesting he won't just be a perimeter specialist. With 19 assists over five games, Knippel's ability to play as a secondary playmaker adds further intrigue to his future with the team.
In conclusion, the Summer League has provided a glimpse of the future stars of the NBA. With promising debuts and skillful performances, these rookies have set the stage for what could be impactful careers as they transition into the league. Each player's development will be closely watched as they aim to carve out their roles on their respective teams.
