Jake Fromm isn't draft eligible, is he?
Herbert is the one I'd be interested in most of all, but I'd also have to think about looking at Bridgewater potentially. I'm sure he's going to be looking for a situation for a one year prove it deal. Would he come cheaper than Joe's cap savings? I'm not sure. I don't know, but I do think he has franchise quarterback potential.
But if you were to release Flacco, Jimmy, and Carr, you'd be saving around $25M. Before any rollover, the Ravens have $35M in cap next year (estimated value). Let's say they roll over $5M; that puts the Ravens at $65M with those releases (although, $35M in money might be a reason the Ravens DON'T release those players; the Ravens aren't hurting for cap.) That's enough money for a new coach to go out and get his guys and start building his foundation.
