There are a lot of moving parts in this comparison. I meant replace, as in, were able to field a competitive defense with some resistance to the run (meaning, better than 2011 or 2013) on the defensive line.
While Raji of 2010 was not truly replaced, I think they had enough big bodies that the "base" 3-4 was fine Daniels-Guion-Boyd.
They do have more penetrators now than before, so short yardage can look a little different now with Peppers, Neal and Jones. However, if Raji is healthy and Pennel somehow makes the team, 3-4 or jumbo 4-4 won't be a problem either.
We'd have to look at the starting roster to be sure, but I think the elephant position, basically Neal, has allowed them to essentially add one fat guy. Neal counts as an OLB and nickel rusher. The last guy in is likely beefier.
