Lakers training camp: Live coverage from Day 4 in Hawaii

And here's how Julius Randle did in the "make 'em or run" game.

And here's how Tarik Black did in the "make free throws or the team runs" game.

Lakers played a free-throw game at the end of Friday's practice. Coach Byron Scott picked a few players, and if they each made both their free throws, there would be no running for the team.

Here's how Jordan Clarkson did...

(Players were told by Scott to jump up and down under the basket while Clarkson was at the line.)

Byron Scott delivered high praise for Julius Randle, but the focus shifted to a younger member of the Lakers.

D'Angelo Russell had to stop about one-fourth the way through Friday's practice because of pain in his right foot. He sustained a bone bruise on the bottom of it the previous day and was also bothered by a blister, Coach Byron Scott said.

Is there reason to fret about the second pick in the draft?

"No, not right now. It's just something that's bothering him," Scott said. "It's just a little sore. I could see that he was kind of limping and favoring it so I just told him to go sit down."

Russell had some orthotics added to his shoes earlier in the day to try to prevent further soreness. It was unclear if he would play in the Lakers' exhibition opener Sunday against Utah.

It was also not known if Kobe Bryant would play Sunday.

"We'll see," Scott said coyly. Bryant did not practice Thursday.

Metta World Peace also sat out because of a sore calf and Nick Young was sidelined toward the end of practice because of a sore back.

Beyond all the injuries was praise for Randle, who looked impressive yet again in day four of training camp.

"He's just so much more explosive now," Scott said. "I think he can be a star. His first step is about as quick as any power forward in this league right now. It's just about developing the rest of his game."

Randle has worked on his outside touch and become more confident when he has an open look, Scott added.

He's also been given the green light to push the ball whenever he takes a defensive rebound.

"His play-making ability I think will come in handy for us, the way he can handle the ball and his speed getting up and down the floor," Scott said." But with that comes a lot of responsibility as far as not turning the ball over a ton of times, either."

It was a natural move for the Lakers with so many young post players, let alone center Roy Hibbert, a veteran known more for his defense than offense.

The team hired James Worthy as a consultant, a "footwork specialist," the Hall of Fame forward said with a smile.

He is active at training camp, trying to pass on the litany of post moves he employed as a player.

"The spin move was a natural for me. I was quick," he said. "But basically what I'm teaching is the basic mid-post drop steps and variations of that."

Worthy learned a lot of his footwork at the legendary Pete Newell camp after a suggestion from former Lakers executive Jerry West.

"He realized I was using my athleticism too much. I used to back people down and turn into them -- Robert Parrish, Manute Bol and those guys," Worthy said. "[West] wanted me to face the bucket, and that's how I got into the theory and science of it. I'm just trying to bring that to some of the guys."

Worthy plans to be present at the team's training facility two or three times a week during the regular season.

He will continue his job as an analyst for TWC SportsNet, bringing up an interesting point: Can he work with Lakers players and yet potentially criticize them on TV?

"I was talking to some guys and said, 'Look, I'm not going to kill you [on the air] on a Tuesday and then come try to work with you on Wednesday.' But I will be constructive," Worthy said.

The tree, me and D'Angleo Russell's foot. Welcome to Day 4 of Laker training camp.
