With the second wave of free agency set to pick up steam, we're looking at an early depth chart prediction for the Philadelphia Eagles

The Philadelphia Eagles may have taken a "major step backwards" in free agency with the loss of several key members of the secondary.

The Lions, who had the best record in the NFL at 15-2 before losing in the divisional round, added cornerback D.J. Reed, and re-signed two of their top defensive free agents in linebacker Derrick Barnes and edge rusher Marcus Davenport. Plus, they have star edge rusher Aidan Hutchinson back from a broken leg.

Taking a look at what the Eagles' defensive depth chart looks like four days into free agency and six weeks before the draft.
