Questions
How long is a basketball game, start to finish?The clock says 48 minutes in the US professional game, 40 in college and international play, but you should budget around two to two and a half hours. The clock stops on every whistle, on every ball out of bounds, for timeouts, and for made baskets in the final minute, so game time and real time pull apart badly at the end.
What is the shot clock actually for?It forces a team to attempt a shot that hits the rim within a set time, 24 seconds in the professional game and 30 in US college. Without it a team ahead by two could simply hold the ball. An offensive rebound resets it to 14 rather than the full count, so late possessions after a missed shot are shorter and more frantic than they look.
How does the playoff format work?A regular season sorts teams into a ranked order, then the top finishers meet in a knockout bracket. Rounds in the US professional structure are best-of-seven series, so a team must win four games, and the higher seed hosts four of the seven. Lower tiers and international competitions often use single elimination or a group stage instead, where one bad night ends everything.
Which stats actually tell you something?Points per possession rather than points per game, because pace inflates raw totals. True shooting percentage, which counts free throws and gives three-pointers their proper weight. Turnover rate and offensive rebound rate, because both decide how many shots a team gets. Raw field goal percentage and total rebounds are the two most commonly quoted numbers and two of the least informative.
Why do coaches call timeout when nothing seems to be happening?To break a run. If the other team scores on three or four consecutive trips without a stoppage, the game's momentum is real in a practical sense: defenders stop talking and shooters loosen up. A timeout stops the clock, lets the coach fix one assignment, and gives everybody thirty seconds of standing still.
