Winning the Super Bowl was great, but one downside is that it put a big target on the Eagles.
Thirty-one other teams are going to be doing everything they can to get to the Eagles' level. Just look around the NFC. You see the Vikings, Saints, and Rams all making aggressive moves so they can challenge the Eagles this year.
Howie Roseman and his staff aren't resting on their laurels. There is no standing still. The Eagles are also doing what they can to get better.
The biggest move wasn't adding a new face, but rather keeping linebacker Nigel Bradham.
