Austin Rivers is on pace to rate 8.1 wins below replacement. -6.5 (Jason Collins, 2006-07) is the lowest mark on record.
From kpelton's twitter. Not sure who he is, but saw this while doing some fantasy bball research. I love Rivers' potential but he isn't ready for a significant role. Hopefully he turns it around once Davis and Gordon get back on the court and take some of the pressure off.
