PHILADELPHIA -- It happens with increasing regularity in the NFL.
A team cuts ties with a veteran and hands his job to a rookie, even if said rookie isn't quite ready to assume the responsibilities of starting.
The Eagles trading Isaac Sopoaga to make way for Bennie Logan doesn't quite fit that narrative, but the rookie is expected to take most of the snaps at nose tackle after the 10-year veteran was traded to the Patriots on Tuesday.
"I learned a lot from Isaac. I take nothing away from him. I wish him the best. But it just shows, I guess, the coaches had more confidence in me and trust me to make that adjustment," Logan said this week. "Now it's my time to accept that challenge."
Logan is expected to start in the Eagles' base defense, which could be on the field a good deal Sunday because the Raiders often employ a two-running back offense. But as Chip Kelly explained Wednesday, parting with Sopoaga also meant giving Clifton Geathers and Damion Square more snaps.
But Logan, drafted in the third round this year, is clearly the defensive lineman the Eagles most want to see at nose tackle. Despite averaging 26 snaps in the first four games, his number of plays dipped to 17 since.
Vinny Curry's increased time has been one reason Logan saw less of the field, but the production hasn't really been there either. He's recorded two sacks, mostly because of pressure created by others, and hasn't gotten consistent push against the run.
Logan's growing pains were to be expected. Typically he would have had a year and an offseason to blossom into a position that requires great strength.
While Sopoaga played the traditional nose tackle role with the Eagles, either lined up directly over the center in the zero-technique or slightly off his shoulder in the one-technique, Bill Davis' defense values versatility up front. Logan has played as much at defensive end.
"In the scheme we play every position on the defensive line is pretty much the same. Everybody does similar jobs," Logan said. "A traditional nose tackle, you'll have a big guy -- 330 pounds or something like that -- but in our defense we do so many different kind of things, it really doesn't matter who plays nose. Sometimes even Vinny Curry will play nose."
The 6-foot-2, 309-pound Logan isn't especially large for a nose tackle. But he has long arms (34 inches) and Kelly has placed great emphasis on that physical trait when evaluating players, especially up front.
"Offensive football is body on body, defense football is body off body," Kelly said."You want to get off of blocks, and it's very difficult if you've got alligator arms and you're in here because you're going to get locked up. You need to get extension. You need to destroy blocks, and one of the ways to do that is to have long arms."
Logan said his arm length surprises offensive linemen and catches them off balance. The 6-foot-8 Geathers has abnormally long arms (38 inches). He had his best game last week against the Giants, recorded three stops against the run in only 14 snaps.
Square, an undrafted rookie, dressed the first two games but was a playing-time casualty when Curry warranted more action.
While dealing Sopoaga creates opportunity for a young cast of linemen, the Eagles didn't pay him $3.25 million over eight games to move up only a few spots in the draft (the Patriots gave their fifth-round draft pick for the Eagles' sixth).
The Eagles likely would have preferred at least a year with Sopoaga as they groomed Logan. Trading the former 49er did save the Eagles $1.5 million. Teams are always looking for ways to save money in the salary cap age, one by-product of rookies playing sooner than later.
Logan, 23, said he wants to be a pillar on defense. The rookie wore the No. 18 jersey at LSU, given to the player that most displays a selfless attitude. Logan has been quietly going about his first season, but he said he's been paying attention to current Eagles leaders Jason Avant and DeMeco Ryans.
"Those are the guys I'm trying to pattern myself after," Logan said. "They're always encouraging the guys on the sideline, in the locker room. They never get down. You can tell they're pros. That's what I think a great leader is. You don't have to talk about it, it just shows."
