Well would point out that restructures aren't the only option. If you cut Bowser, Ricard, and Hill, that's $12M in cap savings alone. Paycuts would also be obvious discussions for all three of those guys.
I probably wouldn't do it if we're moving on from Stanley, but cutting Moses is a possibility also. That's $5.5M in savings, and you have Mekari and Faalele on the roster for cheaper.
In addition, there are cap reductions to be had (in the short term) if you sign extensions with some of your expiring guys (OBJ, Zeitler, namely. OBJ in particular you could be cutting his cap hit in half nearly if you get him to agree to stay on a much cheaper contract.
And speaking of paycuts, I wouldn't take the idea of Stanley being asked to take a paycut off the table either. He's owed $15M next year, and I don't know if he could get that on the open market with his injury history and performance this year. A better overall "outcome" would be to broach Stanley for a paycut, keep him, and draft a Tackle at some point in the draft (meaning it doesn't have to be a first rounder).
The one true thing we don't know is if the Ravens will continue to use void years (my guess is they won't). If they're willing to do max void years on many deals, like they did with OBJ, for example, they can really do whatever they want.
