Thursday's must-see game

Boston Celtics vs. Memphis Grizzlies, 10:30 p.m. ET (ESPN2)

The final game before the start of tournament play at the NBA summer league matches two of the four remaining undefeated teams, as the Celtics and Grizzlies have each won their first three games. That's more predictable for Boston, which has three draft picks playing key roles (Carsen Edwards, Tremont Waters and Grant Williams), along with 2018 first-round pick Robert Williams III. Memphis has a couple of veterans in Bruno Caboclo and Ivan Rabb ,plus first-round pick Brandon Clarke.

Carsen Edwards | PG | Boston Celtics

Edwards, the third pick of the second round, has been one of the most impressive rookies in Vegas over the past week. He has averaged 19 PPG while making 48% of his 3-point attempts and 64% of his shots inside the arc. Edwards hasn't done much playmaking, leaving those duties to fellow second-round pick Tremont Waters as part of a dual-point guard lineup, but it's impossible to argue with his success as a scorer.

What happened in Vegas: Wednesday

Pelton: Scouting Coby White's summer league highs and lows

During the second quarter of Wednesday's NBA summer league matchup with the Charlotte Hornets, I observed to the person next to me that Chicago Bulls rookie Coby White would probably shoot 4-of-13 from the field, but all anyone would remember would be the four makes. I was wrong; he finished Wednesday's game 4-of-17 shooting. But that dichotomy summarizes a week in Las Vegas in which White has impressed without scoring particularly efficiently.

A series of minor injuries and the effect of trades that could not be completed until after the NBA's moratorium period ended on July 6 have left White as one of the highest-drafted rookies in regular action this summer. No. 3 pick RJ Barrett of the New York Knicks is the only player taken before White (No. 7) to play in more than one game so far, and White has played all four of the Bulls' games.

Silver: NBA needs 'enforceable' free-agency rules

NBA commissioner Adam Silver said multiple times during his annual news conference in Las Vegas during NBA summer league that the NBA has "work to do" when it comes to free agency and the rules governing it.

Silver's comments came after a free-agency period in which several star players changed teams through deals that were apparently agreed upon before the official start of free agency at 6 p.m. ET June 30.

Expectations 'growing' for new-look Nets

Brooklyn Nets general manager Sean Marks, sitting alongside head coach Kenny Atkinson, spent a half-hour discussing what has been one of the more eventful offseasons in the NBA -- one that saw Kevin Durant, Kyrie Irving and DeAndre Jordan choose to team up in Brooklyn. The fact that they all agreed to do so at the stroke of free agency was one of many signs that this summer was a lot different from past ones.

What happened in Vegas: Monday

Zion understands the big picture

Zion Williamson took in the New Orleans Pelicans' Monday night game from the sideline, having been shut down after playing just nine minutes on Friday. The team said he knocked knees with another player in Friday's game and suffered a bruised left knee.

"It was more precautionary," Williamson said of sitting out the remainder of Las Vegas Summer League.

Victor Oladipo's injury made him appreciate the game more

Indiana Pacers guard Victor Oladipo, who suffered a ruptured quad tendon in his right knee in January and was lost for the rest of the season, dropped into Las Vegas Summer League looking spry, energized and slim.

Although Indiana's franchise player would not predict a return date, he said he has been strenuously training in Miami with Micah Lancaster and Bryce Stanhope from ImPossible Training and has amped up his skill work, including shooting, dribbling and defensive slides.

Pelton: Scouting the Pelicans' potential NBA draft steal

While Zion Williamson's summer was cut short after less than a half of basketball due to a knee bruise, Monday night saw the long-awaited debut of the Pelicans' other two first-round picks. Because they were acquired via the Anthony Davis trade (and a second trade with the Atlanta Hawks), No. 8 pick Jaxson Hayes and No. 17 pick Nickeil Alexander-Walker were previously unable to play for New Orleans. So too was second-round pick Marcos Louzada Silva.

Before Monday's game against the Chicago Bulls, a member of the Pelicans' front office said the rookies were so excited to play that Alexander-Walker had to be reminded to breathe when he got on the court. They proved to be worth the wait, stealing the show in a blowout 109-72 win over the Bulls. Let's take a closer look at what we saw from New Orleans' other three rookies.

The Clippers' polarizing pursuits of Leonard and George

Kawhi Leonard's choice to join the LA Clippers might have been surprising considering he became the first NBA Finals MVP to leave the team with which he had just won the Larry O'Brien Trophy and because he picked L.A.'s other NBA franchise, but many saw it coming.
