Thanks to a mechanism built into his contract last offseason, cornerback Brandon Carr's $14.3 million base salary was reduced to $715,000 with the difference of $13.5 million converted to a signing bonus. That move alone saved $10.8 million in salary-cap space for 2013.
All told, the moves add up to between $20 and $25 million in salary-cap savings. Just like that, the Cowboys are under the cap without touching Romo's contract. Whether all of the activity is enough to make a run at keeping linebacker Anthony Spencer off the market remains to be seen. We wouldn't count on it.
