EL SEGUNDO — While his teammates played a spirited scrimmage one day after the Lakers’ worst loss in franchise history, D’Angelo Russell tossed up gentle flat-footed shots on the sideline. His right leg was wrapped from his quad to his ankle.No rest for Russell, even when he’s injured. Russell is expected to be sidelined for 1-2 weeks with an MCL sprain, calf strain and bone bruise, but he downplayed the injuries Monday at practice. The second-year guard said it’s the calf strain that’s giving him the most trouble. He feels almost no pain in his knee and feels grateful that it avoided serious injury. “It’s not that big of a deal,” Russell said. “It’s not that serious.” Newsroom GuidelinesNews TipsContact UsReport an Error “There are going to be nights like that, but there shouldn’t be nights where we don’t compete,” Ingram said. “I don’t think I competed at the level I should have.”Ingram lamented his lack of aggressiveness with the first unit. When he tried to manufacture it, he found himself forcing difficult shots.Head coach Luke Walton said Ingram’s game is best suited for a second unit that is more free-flowing, but is still encouraged by his progress. In 12 games during the month of January, Ingram is averaging 11 points, the most for a single month in his short career thus far. “He’s had a couple of bad games, but you get 10-year vets who have bad games, Walton said. “He’s 19 years old, going from point guard to small forward, figuring the whole thing out. So we’re very happy with where Brandon is at.” Figuring it outFor Walton, the most frustrating part of the Lakers’ loss to Dallas was the lack of effort. His team never punched back and mustered the run NBA coaches always believe will come. The defense posed no serious threat to a Dallas offense that featured seven double-digit scorers. The ball stuck like the cars fighting through flooded L.A. freeways Sunday. Coming off a win against Indiana, the coach said his team relaxed into its “natural state” at the smallest sign of success.“In this league, with as much as we play, if you win one game, you gotta let that go by the next morning,” Walton said. “Whether it’s practice or shootaround or on the back-to-back, you gotta be ready to start over, refocus and bring that same type of energy level again the next night out. We haven’t figure that out as a group yet.” The 20-year-old suffered the injury last Friday against the Pacers and sat out of the team’s 122-73 loss to Dallas on Sunday. After he missed 12 games in December and November due to a left knee injury, Russell said he better understands the patience it takes to recover and the importance of just getting a few shots up, even if they’re alone in the corner. “It takes time to get back into the groove that you’re in,” he said. “You miss one game, two games, any games, it’s hard to come back from. So knowing that it’s going to be a tough getting back into the groove, there’s better preparation going into that.” Ingram finding rhythm in first unitAlready startled by his team’s 49-point loss to Dallas, Brandon Ingram grew more frustrated when he saw the box score of the most lopsided loss in Lakers history. Beside his name, he saw that his plus-minus was a gaudy minus-45, meaning the Mavericks outscored the Lakers by 45 points when the 19-year-old rookie was on the floor. In his second career start as the primary ball handler, Ingram scored six points, picked up five fouls and turned the ball over three times without an assist in 36 minutes. He called the dismal performance “out of character” for himself, but wanted to remember it as motivation.
