The International Olympic Committee recently announced that 3-on-3 basketball will be an Olympic sport at the Tokyo 2020 games. 3-on-3 is played entirely in the halfcourt with a 10 minute game clock. Each team has four players, three starters and one sub. Players score 2 points for any shot taken outside the arc and 1 point for any shot taken inside.
Who does well in a 3-on-3 game? Ideally, you want a big man with guard skills because outside shots and layups are extremely valuable. Karl-Anthony Towns would do extremely well in a 3-on-3 tournament. As a result, a super small player may not be tremendously effective in 3-on-3 even if they were incredible in 5-on-5.
