Cowboys and Redskins were penalized for front-loading contracts in the uncapped year. They both take major hits in salary cap over the next two years. Which is divided between 28 teams, so most teams get an extra 1.6 million more in cap space. http://www.nfl.com/news/story/09000...from-cowboys-skins?module=HP11_headline_stack
Not in that article, but reported elsewhere, the Saints and Raiders had minor violations and won't get any additional cap space, which is why only 28 teams get added cap room instead of 30.
