Brooks, who I've come to really like after listening to his draft tracker podcast, has the Eagles taking Georgia LB Jarvis Jones. As a guy who played and flourished as an OLB in a 3-4, he'd be a pretty easy fit as the Eagles look to transition to that front.
While many feel that Brandon Graham has the skills to play in a 3-4, the reality is that he hasn't done it. He was a hand on the ground 4-3 DE in college and has been the same in the pros. Trent Cole has been a 4-3 DE for his entire career and at this point you'd have to figure he's less malleable than the younger Graham would be. So having a blue chip guy that will instantly be familiar with the system would be a big aid as the Eagles make the shift to a 3-4.
Jeremiah, who scouted for Howie Roseman and therefore should know a thing or two about how he thinks, has the Eagles taking Alabama CB Dee Milliner. Certainly the Eagles have put a premium on the CB position during the Reid era and while that era is over, it is where Roseman came up. Plus, CB is a premium position in virtually any defense, it's a big need for the Eagles, Milliner is the consensus top guy, so it's really not a stretch to see why the Eagles would take him regardless of their history.
In Davis's mock, the Eagles take Utah DT Star Lotulelei. Really, you can apply the same logic as the Jones pick from above. Star is a blue chipper who could slot in at NT in a 3-4 from day one. The team doesn't have anyone currently that's an obvious fit for that spot, so taking Star here would be both a big need pick and a tremendous value for a guy that some see as one of the top 2 or 3 talents in this draft.
