The wide nine created a great pass rush, as the Eagles tallied 16 sacks in the first four weeks, the best in the league. It left even bigger holes in the line, which led to teams gashing the Eagles. The wide nine can work with great linebackers and the right personnel. The Eagles clearly do not have the personnel to make it work.
That's the bad news. The good news is the Eagles may have finally figured that out. They abandoned the wide nine for the most part in the second half vs. Buffalo and went to a more traditional 4-3 set up. That worked wonderfully, as the defense shut Buffalo down in the 4th quarter and most of the half. Hopefully, Juan Castillo and Andy Reid noticed.
My guess is that they did and the Eagles play a more traditional 4-3 this week. That will play to their strength as they will do surprisingly well in playing their best defensive game of the season in what will be an Eagles victory.
Final prediction: Eagles 31 Redskins 17
