The chances of the Eagles' coming away with an impact safety Thursday night in the first round seem to diminish by the day. On Thursday, Howie Roseman dropped some big hints when he called the safety class “not a good overall group.” He then spent a few minutes talking up his in-house guys, especially free-agent signing Malcolm Jenkins and incumbents Nate Allen and Earl Wolff. Mike Mayock of the NFL Network suggested that of the two of the first-round-caliber safeties, only one really fits the Eagles’ defensive scheme. But he also expects former Alabama safety Ha-Ha Clinton-Dix to be off the board before the Eagles pick at 22. “I think Clinton-Dix will definitely be off the board,” Mayock said. “[Calvin] Pryor may or may not. I'm not sure Pryor fits what they do.” The book on Pryor is that he’s more of a free safety who makes more plays outside the box than inside. The Eagles, under head coach Chip Kelly and defensive coordinator Billy Davis, prefer their safeties to have the versatility to play inside and outside the box and also move into the slot and cover tight ends. If the coaches don’t have interchangeable safeties, they can’t be as creative or selective in their blitz and nickel packages. In the second round, Mayock said Northern Illinois' Jimmie Ward and Florida Stat'’s Lamarcus Joyner would be appealing to the Eagles because each can play both positions. After those two, pickings are slim.
