"Technique beats tactics." - Gregg Popovich
Measure progress with video. Identify the positives and need areas.
In an earlier possession, white came out in a diamond press. What is it this time? It appears to be "run and jump" which I think of as "trap and go."
Among Dean Oliver's "Four Factors" the most important is differential field goal percentage. The path to improved field goal percentage runs through quality passing and shot selection. Everyone decides what makes quality shots for their team.
Transition defense. "Basketball is not a running game, it's a sprinting game." As a player ask yourself, "did I sprint back at full speed, fully engaged?"
What is the offense trying to do? Is the defense neutralizing penetration, denying the middle, getting hands in the passing lanes? Ultimately, the defense forces a turnover.
Offense creates and exploits advantage. Tight on-ball defense (not here) invites screens and tighter off-ball defense invites back door cuts.
The closeout isn't under control and the ball handler seeks to exploit that. Could the finish have been better accepting some contact to draw free throws? Maybe.
The defender does a good job shutting off a possible back cut down the middle.
The enemy of good is better? Maybe I'm nitpicking but perhaps a little quicker roll while presenting a good hand-up target gets more separation and two points.
A live-ball turnover with a 'hockey assist' on a look-ahead pass earns two points in transition.
