Drop Julius Peppers?

Peppers has been a downer all season.  In my league we start 2 DB, 2 DL, and 2 LB.  My other DL is Cameron Wake.  I'm in a situation where there is a 5 or so man run for the bottom two spots in the playoffs, I need all the help I can get (I am the front runner).

DL options I could pick up from FA/WW are: Chris Clemons, Michael Bennett, Tuck & Umenyiora, Babineuax, etc.

Hold to hope with Peppers for the last weeks here or get rid of him?  The problem is, he is a veteran player and knows what the hell he is doing.  During games instead of getting the points himself he does a great service to his team and creates openings for the other guys.

I should add the scoring I suppose:

Tackle: 2 points
Assist: 1 Point
Sack: 3
Interception: 2
Fumble Force: 1
Fumble Recovery: 2
etc. the rest don't really matter too much, mainly the first 3.

Also Jabaal Sheard is starting to pick up and he is available, facing against Oakland and the Chiefs here in the next two weeks.

I'd go with Clemons as he has the Bears this week and the Cardinals next week. Two of the best matchups for DLs this season.
