Smart not a PG. His ball handling is terrible and doesn't do anything elite on offense. He is more of a 3-D SG if he reach his potential which I doubt because it is looking like he is injury prone.
Injury prone? He's had a few unrelated injuries due to his style of play, but nothing that looks chronic or long-lasting.
And idk what games your watching, but Smart's ball-handling has never been terrible, and has significantly improved this year to the point where it's probably slightly above average. It will continue to improve. His ability to get to the rim has also improved, and as he adjusts to learning how to bully his way to the hoop in the NBA he'll keep getting better at it. I'm not 100% sold on him being a full-time PG, but that's not what Brad wants anyway (He wants multiple creators on the floor at all times) so I'm not sure how much that really matters.
Just about no one works harder than he does, he'll continue to improve and develop into a good offensive player. Maybe not great, but good enough to supplement his defense. He's got a far better offensive skill set than Tony Allen's ever had, for example.
It's easy to overlook defense, but it should never be overlooked. Smart, at 21 or whatever he is, is already one of the best perimeter defenders in the entire NBA. He's like a defensive savant, the total package from a back-court defender with a motor that just never stops. He has future All-NBA defense written all over him. People need to be patient with young guys like Smart and Young who are gonna need time for it all to click.
