He knows that a good chunk (majority?) of NBA fans will NEVER put him over MJ.
He would have had to win 7 rings in 7 trips.
People can say "naw, that's bullshyt" but that's facts. MJ is that favorite of Boomers, Gen X and Reagan Baby Millenials (1980-1988). Even if Bron never did a super team, stayed in Cleveland and won... say 5 rings in 8 trips, he'd be viewed like Kobe. Respected but not #1.
Now he's just gonna stat pad until every record is out of reach. Dude is #1 in points and like 4th or 5th in assists. He's petty like MJ and this is how he will show it.
