These are guys who have actually played a lot the past 5 years combined (minimum 8000 minutes) and have contributed the least (based upon being bottom 10 in WS, poor WS/48 and PER).
I give 10 points for being the worst in a category (WS. PER, WS/48) down to 1 point for being the 10th worst.
10th worst -- Vasquez (8 points)
9th Worst -- O.J. Mayo (10 points, wins tiebreaker due to more WS than....)
8th Worst -- Luke Ridnour (10)
7th worst Kirk Hinrich (15)
6th worst -- Al-Farooq Aminu (15, fewer WS than Hinrich, but more WS than....)
5th Worst -- Mo Williams (15 points, loses the tiebreaker due to fewer WS than the guys in 7th and 6th)
4th worst -- Brandon Knight (16 points)
3rd Worst -- Evan Turner (22 points)
2nd Worst -- John Salmons (25 points)
And, the least productive guy to play 8,000 minutes or more the past 5 years.....
#1 -- Wes Johnson (28 points, the fewest WS, the worst WS/48, and the 3rd worst PER of the group).
