LeBron said it was disrespectful to other rivalries to call him and Steph Curry rivals. His point was they haven't had enough battles.
Some would probably say it's a dick move by LeBron, because while that it true, they haven't had enough battles, we all know he's really saying that Steph isn't on his level. That's also true.
I would respect LeBron a lot more if he would just come out and say, "we aren't rivals because Steph isn't on my level. He just blew a 3-1 lead in the Finals."
A statement like that would be way more authentic and to the point than him just saying, "we haven't had enough battles."
