There are guys who have played in Jim Schwartz‘s scheme the entire time he’s been the defensive coordinator of the Philadelphia Eagles who are still adjusting to some of the complexity. Then, there’s middle linebacker Dannell Ellerbe. He’s been on the team for a grand total of about three weeks.
Ellerbe owes his roster spot, primarily, to Jordan Hicks being lost for the season. He’s spent time on both the Baltimore Ravens and Miami Dolphins roster.
