What It Means:

Cotton had a -0.3 nERD in 15 games as an undrafted point guard for the Jazz last year. In seven summer league games he's averaging 15.4 points, 3.9 rebounds, and 4 assists. Cotton has Player Efficency Rating of 28 which ranks 18th in all of summer league, although his 45.3 Effective Field Goal Percentage leaves something to be desired.

Jazz second year point guard Trey Burke had an awful -4.7 nERD last year, which means he would make a league-average team almost 5 games below .500. The Jazz certainly have room for improvement at the point.
