I think you can't have sufficiently informative technical commentary within the constraints of the current television coverage approach. That approach mostly relies on part-time commentators who have undeveloped television skills, together with a reliance on the watcher to know what is going on in order to appreciate the spectacle on court.
Commentary that adds real value has to both entertain and inform to get the biggest audience. Technical commentary works best when there are good visuals designed to accompany it, such as using replays and on-screen mark-ups to demonstrate how specific tactics affect the game.
Cricket coverage does this well, for example, with things like batsmen's scoring wheels, bowlers' length/line graphics showing dot balls, wickets and boundary balls. USA gridiron coverage also does it well. Both of those sports benefit from regular breaks in play in which to present those graphics/replays with accompanying technical commentary.
Sports like basketball and AFL don't have the same regular breaks. However, arguably basketball has opportunities through time-outs (up to 8 per game I think), fouls (around 45 per game), and video replay delays (one or two per game this season). There are also quarter time and half time breaks. So more than 55 opportunities per game with 30 to 120 second breaks or longer.
Consider the current practice of sticking mikes into time-outs, to hear what the coach says to the players, maybe with some shots of X's and O's on a whiteboard. Does any of that mean anything to a watcher with little or no basketball playing experience? Would it be better to show 90 seconds of visuals breaking down how one team is successfully running its offence with commentary on how the other team could combat it, then have a boundary rider give a plain English summary of the coaches' time-outs as the players return to court? I think it would.
The issue then becomes having the on-hand resources to prepare those graphics and replay materials along with the commentary expertise to analyse and rapidly prepare their narrative outline during the game. That requires much more technical support than the broadcasters and NBL are investing in game coverage.
