Life moves fast in the NBA, and after the much-hyped draft and a flurry of offseason moves, Summer League is already here.

Attention turns to the California Classic today, with the San Antonio Spurs battling the Miami Heat before the Los Angeles Lakers take on the Golden State Warriors Blue squad, and it’s a first opportunity to see some of the late first-round rookies in action.

Let's dive into my NBA Summer League predictions and free NBA picks for Friday, July 3.

Today's Summer League Picks

Spurs moneyline (-127 at Kalshi)

Although none of the San Antonio Spurs’ young core will be in action at Chase Center tonight, that clears the way for Tarris Reed Jr. and other members of the San Antonio rookie class to ball out.

Reed Jr., the No. 26 pick, averaged 14.7 ppg and 9.0 rpg last season at UConn, and I expect him to seize this opportunity to make a case for bench minutes next season behind Victor Wembanyama.

Though Jayden Quaintance will miss out for the Spurs, second-round picks Ja'Kobi Gillespie and Mailq Brown should get minutes here, and San Antonio’s serious approach to summer action could be seen in its 5-3 record last year.

While the Miami Heat can turn to Myron Gardner — who appeared in 45 NBA contests last season — the trade for Giannis Antetokounmpo leaves Miami with fewer young pieces for a Summer League run.

Of course, the Heat specialize in discovering undrafted gems, but they face an uphill battle in this California Classic opener, and I’m taking the Spurs up to -140.

Lakers moneyline (-108 at Kalshi)

The Los Angeles Lakers have been busy undergoing roster reconstruction over the past few weeks, and now attention turns to the end of the bench, where spots are up for grabs. L.A. enters as a major underdog against the Golden State Warriors, but I’m expecting an upset in California.

Golden State can unleash rookies Yaxel Lendeborg and Alex Toohey alongside sophomore Will Richard, but don’t sleep on this Lakers squad, with Cameron Carr — the No. 24 selection in last month’s draft — running the offense and Adou Thiero looking to boost his stock.

Thiero had some promising flashes during last season’s injury crisis in Lakerland, and there’s a 3-and-D role within reach if he catches the eye in Summer League.

Meanwhile, a rookie-heavy roster will get a jolt of experience from Zhaire Smith, with the 27-year-old former first-round pick auditioning for L.A. this summer.
