When a team loses possession of the ball prior to shooting or scoring, it's a turnover.
A team that rarely turns over the ball has more possessions and chances to score. The more chances you have to score, the better opportunity you have to win.
What percent of a team's possessions result in a turnover?
The answer is a team's turnover percentage.
TO% = TO / Possessions
For example, in the 2016 First Round NCAA Tournament game between West Virginia and Stephen F. Austin, West Virginia turned the ball over 22 times over 70 possessions.
West Virginia's turnover percentage was 31%.
TO% = 22 / 70 = .314 * 100
This means around 2 out of every 6 West Virginia possessions ended in a turnover.
Turnover percentage is pace-independent.
This means how fast or how slow a team plays has no bearing on its turnover percentage.
Why is this important?
A team's philosophy has a lot to do with how many possessions per game it averages.
For example, Virginia averaged around 63 possessions per game in 2015-2016.
North Carolina averaged almost 9 more a game (72 possessions per game).
If a team averages more possessions per game, there are more opportunities to turnover the ball. Pace of play doesn't help or hurt a team's turnover percentage.
Turnover percentage doesn't factor in pace of play.
On the other side of the ball, an opponent's ability to force turnovers can play into a team's turnover percentage or how it avoids turnovers.
If a team has a bad turnover night, remember, it's likely equal parts of bad offense and good defense by the opponent.
This means if a team is good at forcing turnovers, the team is probably helped by its opponent's poor offense too.
