The study: https://www.sciencedirect.com/science/article/pii/S1469029224000219?via%3Dihub

We find that the extent of touch (i.e., being touched by 0, 1, 2, 3, or all 4 teammates) after the first free throw predicted success with the second free throw, but only when players missed the first free throw.

We argue that this means that teammates’ support expressed in physical touch helps particularly when stress levels are already high

The study data were women’s NCAA basketball. In about 60% of cases the shooter was dapped up by 2 of 4 teammates. As a Raptors NBA fan, if I don’t see four daps I’m curious who’s absent and why lol. They’re usually tying their shoes or the coach is talking to them on the sidelines
