Look Who's at the top! 1. Wesley Matthews, Portland Trail Blazers 2013-14 WARP rank: 34 The only thing that keeps Matthews from leaping into the league's top 20 players is his below-average volume, as he sports a career usage rate of 19.1 percent. With the Portland offense understandably focused on Damian Lillard and LaMarcus Aldridge, that's not going to change. However, Matthews deserves credit for being an efficient supporting player, one who could post eye-popping averages should he ever be asked to carry a larger load.
