Pedigree was on the Los Angeles Lakers’ side in Saturday’s summer-league opener in San Francisco. Shooting clearly was not on the Miami Heat’s side, in what turned into a 100-66 loss at Chase Center, home of the Golden State Warriors. Against a summer roster that featured Scotty Pippen Jr., son of the Hall of Fame forward, and Shareef O’Neal, son of former Heat center Shaquille O’Neal, the Heat shot 5 of 18 from the field in the first quarter, 9 of 44 in the first half, closing at .280 from the field. “It’s a rough score to look at,” said Heat assistant coach Malik Allen, who is guiding the team’s summer roster. The Heat are playing the three games at the California Classic with somewhat of a B Team, with Omer Yurtseven and Marcus Garrett to join the roster in a week for the upcoming Las Vegas Summer League. “We just didn’t get in a good rhythm,” Heat first-round pick Nikola Jovic said.
