Nothing is that pressing, really. But this is where you get into how strongly Eagles general manager Howie Roseman believes in taking the best players available, regardless of position. And an injury to any of the starting trio could change the picture dramatically.
Some mock drafts have Notre Dame nose tackle Louis Nix (6-2, 331) going to the Birds at 22nd overall in the first round. Nix is bigger than Logan (listed at 6-2, 309) and might provide more pass-rush push. Logan, a third-round rookie last season who showed a lot of promise, can also play defensive end, so it isn't like he'd never see the field again if Nix was the pick. But if the team rates, say, a corner and a wideout as comparable to Nix in terms of potential, wouldn't the Eagles be better served shoring up those positions? To be the pick, Nix probably has to rank way ahead.
The Eagles probably aren't going to have a shot at Pitt's versatile, quick Aaron Donald. It'll be interesting if they do, given that the Birds are trying to get bigger, and Donald is listed at 6-1, 285.
If he's there when they pick 54th overall in the second round, or 86th in the third, it'll be interesting to see if the Eagles go for Missouri defensive end Kony Ealy (6-4, 273), who has that long, lean frame that seems to be their prototype. Ealy might project more as a linebacker in the Eagles' scheme; that's the case with quite a few of the college defensive ends.
