I disagree with you. You are completely overlooking his once in a generation passing and vision, great rebounding for a point guard and he is playing really good defence(especially team defnece). He proved he can be a decent shooter in college and he had a 16 game stretch with around 50% from the field and 45% from three this season. To me it is a confidence problem. As a Lakers fan, I want him to keep shooting and shots will evetually start to fall. About free throws, that's just terrible I agree, but that is fixable as well. Final point- he has been compared to Jason Kidd. Kidd shot 27% from three in his rookie year and we all know what he turned into. Surround Lonzo with better shooting and he will be a consistant triple-double guy.
Anyway, good post, glad to see different opinions. Best regards!
