Small sample size. Very small. I think this is an aberration. His last game, he only got two minutes before injury. He is a 4 assist guy really. Probably more. Its a legit question to ask though.
He is a ball dominant "PG" that's fits the mold of the vast majority of "PG"s that come out these days. There's a lot of Kyrie Irving in Garland's game. I agree that his assists will approach a more normal level when he puts on an NBA uniform. To me, he falls into the Marbury type of passer; that is, he only seems to pass when it makes him look good. It's as common for this era as it is revolting. He does have some natural passing instincts, but he seems less interested in that than he does scoring. Absolutely a score first PG.
To add, he doesn't give a rip on D. With his quick twitch movement he should excel on D like De'Aaron Fox did. However, we haven't seen it yet. I don't have high hopes that he'll figure it out... again, Kyrie Irving.
Yes, the kid can flat out score. He's got all types of O. And for that reason alone, he'll probably "shine" and make people lament passing on him. However, for those who truly look at a player for ALL he has to offer, I think he'll come across more as a stats guy than a winner. My guess is that he's a 20ppg/6apg/4topg kinda guy with a horrendous Drtg.
He's a terrible fit next to Book. He's not a pass first guy. He doesn't play D. He needs the ball in his hands to be effective. The last thing we need is a guy who is a ball hog AND is a raw project.
Oh... and I get that this era is fine with carrying, but sheez. At least try to hide it. Garland might set a record for the most carries called in his rookie season.
