The Dallas Cowboys are set to lose $10 million against the cap over the next two years, while the Redskins are set to lose $36 million. According to ESPN:
During the pre-lockout 2010 season, the collective bargaining agreement expired and the league operated without a salary cap.
According to sources, the Cowboys and Redskins took immediate cap hits during the 2010 season that normally would have been spread out over the length of the contracts, giving them an advantage that other NFL owners found unfair.
Putting all biases aside, this is total B.S. The Cowboys and Redskins both took advantage of the uncapped season and reworked contracts accordingly. Now Goodell is punishing them retroactively for something they did that was not against the rules.
That being said, it makes me smile to see Dan Snyder get screwed out of $36 million in cap space right after he trades away draft picks that are more precious than ever after the latest CBA.
