I understand why people want to take a look at this but after watching the video again, I don't see anything wrong with what Smart did, nothing, period. Not reckless, not dangerous, not dirty. And someone tried to compare this to a failed attempt to block a shot, something desperation or unnecessary (fake hustle?). But Smart got the ball, got it to Tatum. It was a successful play at a point in the game where it mattered.
This is exactly what every coach would want every player to do, period. I am sure it is what Kerr would like his players to do. It is probably what Kerr would have done himself back in the day, or at least his coach would have wanted him to do.
The play where Smart blocked a shot and fouled (I think it was Thompson) with his foot if far more debatable than diving for a lose ball. Smart got a flagrant for the "foot block" (never seen that before). I thought that play deserved a flagrant, that was fair enough, but even that play was not egregious. Smart was falling to the floor. It was as much a collision as anything but the result was a kick to the arm so I felt the call was fair.
