One of the best players the Ravens lost in free agency was defensive tackle Arthur Jones. Pro Football Focus (subscription required) gave him a plus-15.7 grade, the third-best of any Ravens player.
Jones left as a free agent. As it stands, Baltimore has Brandon Williams, DeAngelo Tyson and Kapron Lewis-Moore to replace him at DT. Lewis-Moore was just a sixth-round pick, but a knee injury suffered in the last game of his college career sidelined for him all of his rookie season.
Williams and Tyson combined to play just 247 snaps, so this is a position with uncertainty heading into next season. One other player on the roster who also has experience at DT is Haloti Ngata.
In a 3-4 defense like the Ravens run, you need a big nose tackle who can line up over the center and occupy space in the middle of the defensive line. Ngata was asked to do that for the first time in his career in 2013, and he did great at it.
But if the Ravens want to move him back to DT, they'll need a new nose tackle to replace him. That's where Louis Nix comes in. The 6'2", 332-pound mammoth can play both DT and NT, giving the Ravens options on how they'd play him alongside Ngata.
While Nix has been projected as a first-round pick by many draft gurus, ESPN draft insider Mel Kiper (subscription required) believes Nix will go early in Round 2 and that a draft-day slide drop could be coming.
Matt Miller's most recent mock draft actually has the Ravens nabbing Nix at pick No. 48, only adding to the belief Nix could slip into the second round of the draft.
If Nix falls to the Ravens in the second round, they won't waste any time making him their pick.
