I get the point both you and Cheese are making here Brian, but consider this:
Gregg Hardy inevitably had charges dropped in his DV case, but the league took it upon themselves to investigate the situation on their own, and dole out punishment HOWEVER they saw fit. Nothing was ever "proven," both sides of the story were never weighed in court, all charges were dropped, he was never found guilty, yet still faces a 8-9 game suspension by the league (above the 6 game just set less than a year ago).
I would argue that, if the league feels free to overstep the legal system/due process, and punish a player in spite of charges being dropped (and yes, I realize there was a payoff/settlement that was reached outside of court which allowed for this), AND punish him more than the 6 games they set forth for 1st time DV, then SURELY they could also weigh the progress/compliance/good behavior Darryl Washington has demonstrated over the course of the last year.
Remember, Darryl pled guilty, took his punishment, and followed through with his rehabilitative process... This crap the league is doing should cut both ways IMO.
