TJ Ward and Trent Cole

1) TJ looks questionable at best and has been so-so the last 3 weeks. Can I replace him with Jordan Babineaux, Atari Bigby, or Charles Godfrey (note: I own McCarthy and Ayers so feel weird starting 3 Titans on defense)?

2) I have Trent Cole, Chandler Jones, and Carlos Dunlap and we have 2 DL spots we start (14 teams). Can I drop Cole or will I regret it and am better off wasting a bench spot, or drop Dunlap? (Jeremy Mincey and Chris Long are free agents so it's not completely barren) Thanks.

I'd keep Ward and Cole. Ward to the other players is a lateral move and Cole has been playing well just not getting a ton of snaps.
