The Tampa Bay Buccaneers made one of the biggest splashes in the NFL's free agency talent pool last year. Now the Bucs are poised to stir the waters in a big way again.

The Bucs have $30.1 million worth of available cap space to work with for the March 12 start of free agency, the fifth most of the league's 32 teams, according to an accounting on NFL.com.

A good chunk of that space – about $23 million – came as a result of the Bucs reworking the 2013 contracts for two of last season's free agent prizes.

Pro Bowl receiver Vincent Jackson and former Pro Bowl left guard Carl Nicks agreed to rework their contracts in a way that turned the majority of their 2013 salaries into guaranteed bonuses.

That allowed the Bucs to pro-rate the bulk of Jackson's $13 million salary and Nicks' $12.5 million salary over the final four years of each player's contract, creating extra cap space for 2013.

"That has actually opened a lot of cap room for us going into 2013 – a tremendous amount," Bucs general manager Mark Dominik said. "We've got a chance to be (heavily) involved in free agency again.
