But I don’t feel like I’m the strongest guy.”Scott likened Black’s strength and work ethic to Denver forward Kenneth Faried. But Scott believes Black will become a “hell of a basketball player” if he develops a 15-foot jump shot and post game. Only two months into his starting point guard role, Lakers rookie Jordan Clarkson has experienced significant growth that had nothing to do with scoring or passing. Clarkson provided a testy exchange with forward Jordan Hill in the waning minutes of the Lakers’ loss on Thursday to Utah. It all happened after Hill’s slow reaction to a defensive rotation gave Trey Burke an open layup for a 74-71 lead with 2:30 remaining. Clarkson believes he must continue holding teammates accountable when the Lakers (17-50) host the Philadelphia 76ers (16-52) on Sunday at Staples Center. “It’s my job being a point guard to be vocal and put people in their places,” Clarkson said. “I kind of got mad at J-Hill because we weren’t communicating.”Lakers coach Byron Scott said he liked “the rookie is more assertive.” Scott also added, “Jordan Hill wasn’t up on the pick like he should have been.” “I don’t think you work on those things during the season,” Scott said. “You work on them, but you don’t put it into play. I don’t think Tarik right now is comfortable doing those things.”The Lakers plan to feature Black on their Las Vegas Summer League team and appear likely to exercise their team option on him. But Black downplayed that he feels uncomfortable expanding his game after spending recent practices working on his shooting and post moves. “I can apply it right now,” Black said. “But I don’t want to all of a sudden change my game and start doing different things and then it changes the flow of the game and then it changes the way the team functions.”This and thatAfter completing stationary shooting drills on Friday, Lakers guard Jeremy Lin believes he will feel “100 percent” to complete all of Saturday’s practice and to play in Sunday’s game against Philadelphia. Lin played in Thursday’s loss to Utah nursing back spasms.Lakers guard Jabari Brown said he will sign his second 10-day contract on Saturday. His first contract expired Thursday evening, but the Lakers waited one day so Brown can play in the Lakers’ entire five-game trip next week. Brown was at the Lakers’ facility on Friday, but he could not practice since he was not under contract. Scott promised to shorten Friday’s practice to just a half hour of shooting drills if any player made a half-court short. The unexpected winner: Ronnie Price shot left-handed while staying sidelined because of surgically repaired right elbow.
