No one on the skins complained. Our legue reps all thought it was totally fine. Some weasle at the players association (I don't even know if it was a player, a former player, or just some pencil-pushing geek) saw a video on skins.com and complained. F*** that.
From skins.com:
The ruling came after an employee of the NFLPA viewed video from Redskins.com and notified the league of their concern that the line work was too physical. League officials contacted the team and required officials to forward video of relative portions of practice for review.
