Not sure the penalties will hamper fantasy numbers too much, but I am concerned about the rule fundamentally changing some guy's running style or their aggressiveness. One guy I can think of is Mikel Leshoure, I remember being concerned for the guys health. Often finishes his runs by completely ducking his head. Bad enough for neck injury danger, but I wonder how the rule will influence his and possibly other's play.
Any fantasy impact for Stephen Jackson or Lynch? Both of them are shifty enough in my opinion that they'll avoid much impact IMO, but still wonder. Any other backs at risk? Trent Richardson and ADP lower the boom sometimes as well.
