Ha! This is a good thread.
This is going to sound really awkward, but here it goes - a much better offensive version and lesser defensive version of Smart.
When I was at my best (after getting tired of being a benchwarmer in college and just playing pick-up and rec ball), I was 5'10" 210 lbs. with 10% body fat. I'm built much more like a football player than a basketball player. I can't jump, I'm slow, and I have t-rex arms, but I have a quick first step.
Offensively, I'd try and overpower the defense on penetration and drives (like Smart), but I was a better ballhandler than Smart and a much, much better shooter. I had 50/40/75 seasons my junior and senior years in basketball, and I averaged 24 and 8 and 22 and 8 those years in points and assists (small school and conference, obviously).
Defensively, I'd play the physical, on-ball D like Smart, and I've always been a good team-defender.
If I played now, I'd look like Sully out there
