The linebacker position for the Philadelphia Eagles going into the 2011 season is completely wide open. There are several projections for the starting three linebackers for the 2011 season. The Eagles drafted three players in the 2011 NFL Draft: Casey Matthews in the fourth round, Brian Rolle in the sixth round and Greg Lloyd in the seventh round.
There's plenty of speed, size and intensity to go around—there just isn't a ton of experience.
Nobody's job is safe.
New defensive coordinator Juan Castillo had no say in what the defense did last year (as he was the offensive line coach), so none of the starting linebackers from last year have any favor with Castillo.
This linebacking core probably has the most depth the Eagles have had since the early 1990s, but it doesn't have the experience to back it up. Three players are going to come out of training camp and preseason as starters, it's just next to impossible to project exactly which three players they will be.
