Wrong with this era? You mean during an era with the most athletic players and advanced defensive schemes, that have been built on the constant exchange of the offensive/defensive power struggle. Not to mention, the basketball public understands what constitutes as good defense a lot more than those during MJ's time in the league. I mean hell, even NBA coaches didn't treat defending the 3-pt shot seriously 25-30+ years ago. And what do you mean by "nobody on the GOAT list did it like MJ did"? Defense? Overall? Because LeBron has his measure in both categories.
Not to mention if we're talking about "complete" player (not necessarily better, but fewer weaknesses/more overall strengths), LeBron certainly has a better argument.
Advanced defensive schemes??? Are you serious? I grew up watching Reggie Miller run full speed thru multiple screens with a defender chasing with maximum effort and other players showing and trapping. Just this past year in the finals I watched KD walk into one lazy pick 30 feet from the basket and the defender (Bron) switched without fighting thru it and allowed for a mismatch. Nothing about today's defense is advanced.
And LeBron is not the more complete player. He's a stat compiler that has the ball in his hands a lot. In fact, when is the last time you've seen LeBron catch the ball with his back to the basket on the baseline and score? There are literally places on the floor that no one expects LeBron's offense to even start from. How often is Bron starting his offense in the deep corner? How often do you see him flash to the free throw line extended and start his offense with his back to the basket 15 feet away? Sure, he's a great player so I'm sure you can post instances of when it's happened, but it's not who he is. I can post 15 min videos of MJ on turn around jumpers alone. There are literally 18 min videos of MJ's footwork alone. 18 min videos of MJ's post moves alone. He didn't have isolated instances where he hit 6 turn around jumpers like Bron did against Toronto and have it look so amazing cause it stuck out. That was simply just a part of MJ's game. And it's not just scoring either. When MJ scored his career high of 69 points, he also pulled down 18 boards, 6 assists, 4 steals, and 1 block. When Bron scored his career high of 61, he had 7 boards, 4 assists,
ZERO blocks or steals. It's fair to say, when you got the best outta MJ scoring the ball, other areas of his game doesn't suffer. Cause he's a more complete player.
And Bron does not measure up on defense. MJ has six seasons with 200 steals, Bron has none. In fact, MJ totaled 123 steals in his last season as a 39/40 year old man. Bron hasn't seen that total since he was 28/29 years old. The smaller MJ has two seasons with 100 blocks. Bron has zero. So no, Bron does not measure up in both defense or overall.
the man said hed have to compromise other parts of his game to be a real 3 pt shooter, Ive never heard any other GOAT shooter say that
