He's been declining for 4½ years abd it's 100% age and injury related. That '18 Christmas game where he popped his groin, remember that was the season after taking Cleveland to The Finals and he had LA in 4th place. But he's never been the same since then...
The thing is most guys with a Year 16 injury, or injury at age 34, the decline is swift and hard. It's been gradual with Bron. He can no longer shake off injuries because he's old, and the accumulating injuries have zapped some of his athleticism; he's losing more by the year...
It's a graceful decline and honestly is incredible to watch, no one at this age or stage has ever done what he's done, his last 4 seasons are the greatest ever for a player at this age/stage...
He's not totally washed though, the last 5 games of the regular season/play-in when they were trying to duck the play-in, he averaged 30.4 on 518/484/833 shooting. The play-in game he scored exactly 30...
He hasn't scored over 30 yet this postseason, but has only scored less than 21 once. You don't go from a 5-game stretch averaging 30, to not being able to score big anymore in an instant. He's picking his spots, bro. He hasn't had to break out the Takeover Mode yet. Inevitably there will be a moment he will need to, possibly in this series, certainly several going forward should the Lakers advance. And I think he still has it and will deliver...
But it's "break in case of emergency" status. Right now he's building the collective growth and confidence of the other Lakers, including AD. So far these playoffs he's 22/10/5 on 48/23/72. He's playing incredibly inspired defense every game, and there's an easy argument he's been the Lakers best player which is a distinguished point from who there most important or most valuable player is---->the Lakers can't reach Championship realization with a suboptimal Anthony Davis...
The Lakers can still win with LeBron in second gear, only occasionally having to rev it into first. They can't win with AD in second gear. You've got to inspire him to be in 1st Gear minimum 4x each series, because when he's playing in 1st, the offense is inconsistent but we're running the offense inside-out thru him, and the defense is frigging All-Time level shyt. You gotta keep him inspired...
LeBron is allowing for that, allowing there other shot creators to shine and playing more off ball, posting up more, providing secondary rim protection and perimeter value, etc. He could still wear all these hats in 1st Gear every game but the Lakers would be finished bro, because it takes away the touches and potential of his teammates...
He's maximizing their potential and picking his spots. When they need him to go into Takeover Mode he'll come thru, bro...
