Not nessecary...
Kearse isn't THAT big of a factor, yes the injury hurts, but your overreacting it. Philly has enough depth on the D-Line, to make it work.
Darren Howard, is a very good player, and Trent Cole(although fucking up last game) is a very solid DE aswell. Cole has 4 sacks already this season. Juqua Thomas, has been playing pretty solid aswell and has recorded a sack each game so far, and a forced fumble. Jerome McDougle needs to come back also, to help spice up the defensive line with Kearse out. But to say goodbye to the Eagles playoffs hopes is down right foolish IMO.
I'm more worried about Lito Sheppard coming back, because the way Eli Manning was able to pick on Hanson, allowing Toomer to have a big game was just sickining to see, and was a big part of the reason why the Giants came back. Hopefully we'll see him back next week.
