Take a look at these [tag]basketball coaching[/tag] tips from Anthony. They are excellent [tag]basketball coaching notes[/tag] that can work with all age groups.
A tip I work on for habit awareness includes keeping the upper body and base aligned. My players are asked to visualize seeing themselves, looking down from the ceiling directly above their head. This tip helps them see the alignment of their head, feet, body and keeping their feet and shoulders aligned. I also emphasize a tandem stance keyed by the tomahawk throwing or baseball throwing stance as a concept. This wide base aspect becomes easier to self monitor.
Watch your players when they line up in their [tag]basketball drill[/tag] work and you will notice that the players active (passer & receiver/rebounder/defender) are reinforcing the correct stance, balance and body position. However while everyone else is standing around waiting for their turn they inadvertently reinforce the opposite bad habits in-between doing the right thing.
Next time your team plays watch the ball carrier change from his/her well drilled ball carrying technique to walking the [tag]basketball[/tag] up in a non-athletic fashion only to return to a more compact, balanced, explosive athletic pose. I consider this an example of unlearning because it is what happens. Do your post-up players stand straight legged with a narrow stance, particularly late in their game despite being well schooled in stance and balance techniques? If your players are fit and disciplined so this isn’t a problem, you as a coach probably have either a consistently competitive or winning team. If not the case, developing a player awareness of when, how and why will yield results.
Have someone who does stats for your team spend a few practices and games looking specifically at stance and body position. See if there is a link between getting boxed out, beaten on the dribble or other errors with stance and body position. If this is so you are probably already doing the right things in terms of technique. The next step is developing the awareness of WHY and link the drilling to their game. During scrimmage draw attention to specific examples, good and bad to illustrate this link.
