LOS ANGELES -- Anthony Davis went from injured to insurmountable; fragile to a force to be reckoned with in the Los Angeles Lakers' 117-105 win over the Memphis Grizzlies on Friday at Staples Center. And his performance -- 28 points, 13 rebounds and 7 blocks in only 31 minutes -- left his team again stumping for his candidacy as the NBA's Defensive Player of the Year.

Davis had exited the game after taking a Jaren Jackson Jr. knee into his right shin area less than a minute into the first quarter. He missed the rest of the quarter and the first several minutes of the second, needing to return to the locker room to receive treatment on the bruised right calf muscle and for hamstring tightness the collision caused.

Then he came back in and wreaked havoc on the Grizzlies' offense -- one of the hottest teams in the league since the calendar turned to 2020 -- holding Memphis to its lowest-scoring output in its past seven games.

"He does everything," LeBron James said of Davis. "He's able to protect the rim, he's able to guard in the post, he's able to switch out to guards. He's able to block shots when guys are shooting floaters and runners. Get steals. I mean, he does everything defensively for us. That's why he's Defensive Player of the Year. He just does everything for us, it's not one thing he doesn't do well defensively."

L.A. really clamped down in the second quarter when Davis made his return, outpacing Memphis 32-19 in the period while holding the Grizzlies to 37.5% from the field.

At times he was charged with guarding the massive 6-foot-11, 265-pound Jonas Valanciunas. On other possessions, he found himself keeping in front of the waterbug-like, Rookie of the Year favorite Ja Morant.

Both players -- Valanciunas was 4-for-11 and Morant was 5-for-14 -- had a rough go of it with Davis patrolling the court.

"He's the best defender in the league from a versatility standpoint and what we can do," Lakers coach Frank Vogel said. "His ability to switch out and mix it up in transition, all of those are areas he impacts the game. He's the best defender in the league, simplest way to put it."

Davis, who came in third for DPOY in 2017-18 while playing for the New Orleans Pelicans, said that the hardware isn't his main motivating factor.

"I'm not playing defense for that, but it is appealing. I mean, that award, I would love to have that award several times before I retire -- which is not soon," he said. "[I am] just trying to set a standard for one, myself, and two, my team, on the defensive end and the rest of the guys will follow. ... I'm talking to guys, covering for guys and I think if I continue to do that I put myself in position to win that award.

"But I just want us to get back to being the defensive team that we are and I know that starts with me with a defensive mindset."

The Lakers, whose defensive efficiency numbers allow 106.2 points per 100 possessions, rank fifth in the league.

That's not good enough for Davis.

"We're going to continue to get better and I'm going to continue to get better and try to position ourselves to be the No. 1 defensive team in the league," he said.

While Davis admitted to Spectrum SportsNet during an on-court postgame interview that he expected his right calf to be "pretty sore and tight" Saturday, he sounded plenty motivated to get right for Sunday.

That's when the Boston Celtics come to town, the team that absolutely drubbed the visiting Lakers the last time they played -- 139-107 on Martin Luther King Day.

"The worst loss of the season for us, we didn't play our best at all, so we remember that for sure," Davis said. "We feel like we owe them. It's going to be a fun game so, they remember that. I'm pretty sure they're thinking like, 'We beat them guys by 40,' or something like that. They're thinking about that, we're obviously thinking about it, so [we are] going to come out a little different."
