I'm ecstatic about Haliburton's play so far. I think he's been the best looking rookie with LaMelo as a very close 2nd. In terms of their long-term potential, I do think LaMelo has the higher ceiling. He's nearly 2 years younger and as someone else pointed, he's never played real structured basketball aside from his time in the NBL where he had the green light against a league of men. I didn't expect him to be this good so far his rookie year, but I think he's proven a lot of his doubters wrong.
He's only 19 years old averaging 24.6mins: 11.5pts 5.9asts 6.4rebs 1.5stls on 40.2/32.4/69.
He's already had 3 double-doubles and 1 triple-double (22pts 11asts 12 Rebs). LaMelo is going to be special in this league. His stats speak for themselves.
However, his higher potential shouldn't take away how anyone feels about Haliburton. His ceiling will ultimately come down to his usage and aggressiveness as a scorer.
