I wrote two articles over the summer pleading for the Eagles to replace Casey Matthews at middle linebacker and you can read it here and here.
In the latter article titled "3 Linebackers Who Could Replace Casey Matthews in the Middle", I proposed Jamar Chaney as the number one choice to replace Matthews.
Finally, the Eagles came to their senses.
Matthews was overpowered and couldn't get off blocks. On Michael Turner's huge, momentum shifting 61 yard run, Matthews was too aggressive, opening up a hole for Turner to shoot through. It was clear it was too early for the Eagles to put their trust in him. I thought eventually Matthews could have excelled at middle linebacker, but throwing a rookie in one of the key positions on defense was just absurd.
Matthews will have less duties as the weak-side linebacker and could be very solid there.
Chaney hasn't been great, but his natural position isn't the strong-side, but at middle linebacker. Some could make the case for him at weak-side as well. Chaney had 16 tackles in his first start in the middle against the Giants. He can be a mainstay at middle linebacker for the rest of the season.
Lastly, Moise Fokou will move back to his natural position at strong-side linebacker, where he proved to be a very good run stopper. Fokou has struggled mightily on the weak-side.
