Learning across domains can expose where we go wrong. Barry Ritholtz's "How Not to Invest" informs structurally problematic and beneficial thinking.
We can't enumerate everything in each category but we can discuss key areas that help define "How Not to Coach." We can’t list everything. But we can identify patterns. I've listed several in each category...
Bad Ideas
- "Any idiot with a whistle can coach."
- OJT and reproducing my coach's system
- Five-year plans
Bad Numbers
- DATU. "That doesn't apply to us."
- Raw data. "She scores 15 points per game."
- The Four Factors working against us.
Behavioral Issues
- Selfishness
- Teamwork
- Sportsmanship
- Off-court issues
Teens often struggle with "egocentric" (me first) behavior. That complicates shot selection, teamwork, and sportsmanship. At the varsity level, coaches worry about academic and substance (especially alcohol) issues. There's only so much positive counseling coaches can do, reinforced by parents.
Good Ideas
- "Playing harder for longer"
- Winning close and late (Offensive/Defensive Delay, Special situations)
- Hard-to-defend actions
- Star in your role
Close games are rarely won by highlight plays. They’re won by:
- Executing late-game offense and defense
- Avoiding bad shots
- Valuing the ball
- Making free throws
- Avoiding unnecessary fouls

But here's the part most people miss:
