Earlier this offseason, the NFL stripped the Dallas Cowboys and Washington Redskins of millions of dollars of salary cap space -- $10 million for the Cowboys and $36 million for the Redskins -- for the way in which they structured contracts in the uncapped year. At first glance, it didn't appear that they violated any rules -- all the contracts were approved by the league office -- but the owners still voted not to rescind the penalties against each team.
Both the Redskins and Cowboys filed a grievance arguing their case but the arbitrator, Stephen Burbank, has ruled against them. The NFL's motion to dismiss the claim was passed, and the penalties will not be rescinded.
As NFL Network's Albert Breer points out, this is a fairly major precedent set by Burbank.
Burbank granting the motion to dismiss means he agreed with NFL's argument that Goodell can adopt measures to maintain competitive balance.
