Detroit Lions CB Desmond Trufant's 2-year deal includes $13 million in full guarantees, still leaves cap room

By swapping out starting cornerbacks this week, the Detroit Lions saved themselves about $3 million in cap space.

The team agreed to a two-year, $20 million contract with free agent Desmond Trufant on Wednesday, then traded three-time Pro Bowler Darius Slay to the Philadelphia Eagles on Thursday.

While Slay's trade left the Lions with a $2.9 million dead cap hit, it also freed up about $10 million in cap room.
