Last week's decisions to start or sit WRs did not work out so well based on KC Joyner's grading system. Texan WR Andre Johnson's 1120 yd/2 TD effort will always rank amongst the best performances by a WR in any given week. To have a negative score on that effort will always be wrong.
Titans' WR Brandon Jones caught five passes for 57 yards. In a typical PPR, that is ten points. A -1 score makes that a miss, and, in combination with Arnaz Battle's positve score and dud of a week, that judgment is further solidified. If Jones is such a bad reciever, he should not outproduce a possession receiver like Battle who has a favorable match-up.
All said, the grades did not help with any decisions. With 12.5% of the season to look at, some adjustments to off-season grades is likely in the offing. I'll be curious to see if this helps with the predicitve ability of the system.
