DTs

I realize you don't get many fantasy points from Defensive Tackles, but I am looking for a good starter/backup.

I have Fletcher Cox and Darnell Dockett for my two starting DTs.

I have a bench spot open for a backup or starting DT. There are some good ones available and I have narrowed it down towards one of these five:

Cory Liuget
Phil Taylor
Michael Brockers
Nick Fairly
Linval Joseph

My first choice would be Liuget, but he is banged up and I don't know his injury status.

Any suggestions?

I like Fairley's upside the most of that group. That's who I would go with.
