DL/LB Help Week 15

I have very strong DL and very mediocre LB cores.  Scoring is 1/tackle, 0.5/assist, 3/int but sacks are 5 for DL and 3 for LB.

We start 2 LB, DL, DB and one IDP flex.

My DL includes Watts, Atkins, and Dunlap. My LB include Freeman, Burris, Lewis, Houston, and Maualuga.

Currently I have Watts/Atkins at DL and Freeman/Burris at LB and Houston (Or Lewis if healthy) at Flex.

I am not sure which Bengal lineman to play against Phi and who I should put at Flex.

I'd play Atkins over Dunlap. I'd put Lewis at flex if he plays. Otherwise Houston.
