I believe how you practice will determine how you play. Teams who are inconsistent usually are teams who practice in an inconsistent fashion- work hard one practice but not another, or work hard one drill but coast the next.
I believe how you play in the first three minutes of a game reflects how you practice.
When good teams go to practice, you focus on basketball. Coaches don't have to focus on motivation, players are motivated. Coaches and teammates don't have to try to figure out moods, players are focused. I have been fortunate to have many good "practice teams", who won many games as a result. One of our absolute best was our 1995 team- as coaches we focused on basketball, the players took care of effort and motivation and chemistry.
