Each stat

Defensive Rating is a metric that considers the amount of points allowed per 100 possessions. Defense as a whole has the strongest relation to team chemistry. Switches and screens require defensive communication, and an understanding of where you need to be to make up for a teammate's mistake.

FG-AST% describes the percentage of field goals made that are assisted. This stat shows how a basket is scored, whether it's because of good passing (understanding of where you teammate needs to be to score), or good iso (inidividual) scoring.

Def Reb% is a stat that describes the percentage of rebounds acquired. For a team to gain a defensive rebound the entire team needs to box out every single one of their opponents.

AST-TNV is a ratio that recognizes the number of assists per turnover. This relates to chemistry because a turnover usually occurs when there is a misunderstanding between players.
