James, 33, started all 82 regular-season games for the Cleveland Cavaliers last season for the first time in his illustrious career.
The three-time NBA champion also averaged 42 minutes per game in the playoffs.
And Lakers coach Walton has revealed he’ll keep checking in on James, adding he’s open to resting the small forward if necessary.
“We’ve talked about the idea of it, and I’ll be in constant communication with him all year long,” he said.
“If it’s a night off, if it’s a back-to-back, whatever it is, if it’s practice.
“Preferably if he’s going to take something off, take a practice off to stay fresh.
“We got him here for four years and we want to be competing every single year that he’s here.
“If we do play him less minutes or he gets a night off, that’s a great opportunity for other players.
“It’ll be an ongoing thing, a feel-out thing as the season is going as far as minutes and whether or not he’s going to take this game off or that game off.”
Walton has been vocal on James’ move to the Lakers, with the 38-year-old claiming the four-time MVP will improve every player on the roster.
“I think they’re going to do great, honestly,” he said.
“Part of what I’m hearing from other coaches is one of the things that makes LeBron so great is he picks up every single person he plays with and he elevates their game.
“I know who our young players are and what they’re about. They’re excited he’s here.
“I think the type of players they are and type of workers they are, they’re going to have a really good year.
“Obviously, it’s going to take time.
“Like every new team that gets together. But that’s part of the fun and enjoying the process, is getting these pieces to fit. I think LeBron will make that easier.”
