Great handle??? Lebron?The league hasn't cared about carrying since... the 70s? It's been rampant for ages.
The rule change most people are talking about is allowing hand checking and cracking down on moving screens, also allowing more time for defenders to stay in the paint.
If they called more fouls on offensive players for initiating contact that might effect LeBron some but not as much as dudes like Embiid, Doncic or Giannis.
He is a strong player with a great handle, the guys I think who would suffer most are dudes who struggle with contact and who use a ton of screens. Golden State would need to change up their offense. Durant would have a much harder time getting space, any of the dudes who take a ton of pull up jumpers and run off lots of screens.
Lebron the last 5 years has been mostly reliant on his strength to get to the rim. Most times its a spin move, which he travels on, there are players who use the spin move but use their pivot correctly. Any touch on him whether there is really a foul or not is a foul for Lebron. That portion of the game needs to be fixed.
KD is 7' and has never had a problem getting a shot off with or without space, his length alone makes him a threat even at this stage of career.
