I can maybe get this opposition from a Celtics fan or Sixers fan, but Lakers fans arguing this is a bit comical. Either 1. You have not watched any summer league game this summer whatsoever. 2. You have off-the-court agenda against Lonzo because of his dad, or the media attention he gets. I can't think of any other reason why a Laker fan would try to discredit Lonzo after the tangible (stats, highlights) and intangible (his overall impact on the performance and morale of the team) contribution he's had so far. If you are unable to assess a talent yourself, then listen to people that actually play the game. All the players have come out saying Lonzo is the best passer and best teammate they have ever played with, and they credit him for their increased success. The coaches are singing the same tune.
If there is a person who should not be taken seriously here, it is obvious who it is.
