The Baltimore Ravens opened up a prairie land of cap space in February when they agreed to a four-year contract extension with pass rusher Terrell Suggs that lifted $4 million off the books.

NFL Media's Albert Breer reported on Tuesday's edition of "NFL Total Access" that Baltimore's front office also tried the same with defensive tackle Haloti Ngata, but to no avail.

The Ravens attempted to lower Ngata's whopping $16 million salary cap hit with a "lucrative, long-term" pact, one that would allow the behemoth to retire a Raven. At 30, Ngata remains one of the league's premier run-stuffers and a versatile lineman, able to play both the tackle and end spots.
