Rivers has struggled with the transition to the NBA, in several ways -- that includes making only 34.6 percent of his shot attempts inside the 3-point line.
In fact, Rivers is on track to make dubious history during his rookie campaign. Two months into the season, Rivers projects to rate nearly seven wins worse than a replacement-level player by my player metric, which would be the worst WARP score in the 34 seasons on record, starting with 1979-80, the first NBA season with the 3-point line.
Of course, to build a historically negative WARP rating, a player has to be on the court in the first place. Most of the leaderboard is made up of defensive specialists whose value is not reflected by their individual statistics. Collins, for example, is one of the players most underrated by advanced box score stats.
Beyond that, the list is filled out by players who were overexposed on terrible teams and rookies whose potential demanded playing time that their performance did not yet justify. Rivers qualifies on both counts. With Eric Gordon out of the lineup, the 5-22 Hornets have few good alternatives in the backcourt despite Roberts' surprising performance. Backup wing Xavier Henry has been nearly as ineffective. The situation will change when Gordon returns to action after being cleared to practice over the weekend.
