I'm struggling with this him too. I've had Cyprien in a dynasty for several years. If he were still with the Jags, I would say definitely keep him. It's hard to predict how he'll perform, from a fantasy aspect, on a new team for which he's only played one game.
My personal philosophy is to cut DBs first. It depends on your scoring setup, but 3/4 of your DL seems like they're functionally the same.
If it were me, here's who I'd definitely keep:
Sorenson, Branch, Amos, Ogbah
Cyprien is a huge question.
I think everyone else is a toss-up and probably replaceable. What's the waiver wire look like?
