No shock here, this is how the game is played. Player gets suspended for doing something stupid, said player appeals, NFL takes part of the suspension away.
And the NFL knows exactly what they are doing. Lets go to the schedule:
Well look at that, Hardy will be back just in time for the game against the defending champs.
The big winner in all this? Tom Brady. No chance the NFL is going to allow Tommy Terrific to miss that game for some missing air after letting the wife beater back.
My guess is Tom ends up with 2 games. Maybe less after this.
