Powers is a UFA, so likely he will be gone for 2017. Webb will be entering his last year, but if we can restructure him to reduce his cap hit, it would be ok. For a 1st year transition, I think he played pretty good. Wright won't be cut as he is signed for a few more years, and the dead money is not worth it.
I expect Dumervil, Arrington, Kendrick Lewis to be cut for cap reasons. We have too many TE's on the roster (Watson, Pitta, Boyle, Gillmore, Waller, Williams). From a cap point of view, Watson is likely the odd man out.
We have 2 really good RB's so I expect us to shore up the O-line. If we can get a Centre in the draft and if we can resign Wagner for a reasonable price, I think it would be good. I would not rule out cutting Wallace as well from a cap point of view, especially if we re-sign Wagner at RT. A move like this will mean, we will go back to our predominantly run heavy offence.
