Stockton and Nash were dribbling thru a lane that was much more congested because of the style of play and with a smaller lane at that time. While maintaining their dribble and racking up assists without turnovers. And there are plenty of good college point guards who are staying under control in the paint and making the assist. IMO, most of the jumping in the air on the baseline is from a player making a move to the basket and getting unexpectedly cut off with nowhere to go. And you would be very limited on where the pass could go, which makes it much easier to defend. I doubt most college coaches are teaching that.
