Can IT play on the hand-check era?
This was the first thing that came to mind for me.
Also, it made me think of a reverse question. If Smart could hand-check other guards all the time would he be a better defender than guys like Jordan, DJ?
The reverse question I thought of is: Would Iverson's defense looked as good if HE played with no-hand-checking?
We are playing in an era when even 'elite' defensive guards like Smart and Bradley can't really stop elite perimeter scorers. They only slow them down. Attacking guards like Lowry, DeRozan and, yes, Thomas score at great volume and efficiency against the best perimeter guards and only get checked if the defense has elite paint defenders.
If Iverson played in this era, I suspect he would score far more efficiently (assuming he also made more use of the 3PT shot) than he did in the 90s ... but he also might look less impressive on defense.
