Took a look at Trent's numbers in my workbook, he will have a dead money hit of $3,335,250 for 2013, savings of $1.321M, but take a cap hit of $6,670,500 in 2014. He was to make $5,587,250 in cap next year.
Wonder why they would do this. Last checked on NFLPA site, they had $24.2M in cap room right now. And they must spend 90% of the cap, There at $113,408,437 right now before the trade. However they carried over $14M, so they may be at the 90% limit, which is based off of the $123M cap, not adjusted cap. Which is 123M + 14.2M.
