I don't see how Correa is an 4-3 OLB or an ILB only, he played exclusively at OLB by the time the reg. season rolled around and trying to force him back into the ILB role is just going to make it tougher for him to be an pass rusher for you, something that the team envision Correa as. They see him as a hybrid but if the Ravens are hoping he develops as a pass rusher. I don't think the Ravens drafted Correa with the mindset that he'll be playing ILB. But that's for another thread.
Also, when bringing up the TEs, OLBs, and other developmental players on the roster, well, that's the whole point for relying on Perriman, I mean you trust Judon, Pierce, Za'Darius, Powers, or anyone else more than Perriman? If we're talking about relying on a young player who will have to step up, then I would like to know who you would have in mind, because I doubt that they've shown a whole lot either. I'd rather rely on Perriman and make investments at OLB/CB and possibly keep BW then rely on Judon, Pierce, Waller, or anyone else for that matter and take an $8M cap hit. It's also not the only position where we have young and unproven players at, TE is a unit but one that will be relied upon, as is NT if you lose BW, same goes towards DE if you manage to lose guy because then you're left with Urban and Kafusi, after that you can even look at the CB group because you would like to have a #2 there, I like Young but he might be relegated to a slot role. We all know Jimmy's injury history. OLB once Doom is cut you're left with ZD, Judon, and Correa, oh, and we'll need a C too because Zuttah is not cutting it anymore. I can legit say that Center is up there with OLB/CB in terms of priority and you might be forced to draft one early because there's no FA's there, after that you have Jensen. Do you feel any sort of confidence in any of these guys? Because I have none in them.
As far as getting Bouye, Ingram, or Perry, I wouldn't go to that conclusion. Usually, I don't think the Ravens would go after paying them, but this year is different compared to last, truth is, a lot of people might be heading towards the hot seat, there's going to be more urgency this year. I wouldn't be shocked if the Ravens cracked open the checkbook for someone. If CB/OLB are a position of weakness for the Ravens again next season, then someone is going to be getting some serious heat. It's been 3 seasons now where the secondary has failed this time and Biscotti was pounding the table for a pass rusher. Maybe Ingram is very unlikely but I don't think anyone is paying Perry, Johnson, or Bouye mega contracts. GB front office runs similar to ours, they'll prioritize players and if they have to let someone go they'll have no problem with that. To get the best you're going to have to pay the best. If the Ravens want to get better now, they might have to pay or put out a patchwork secondary again because a 2nd round CB might not even solve your problems there.
Getting a cheap and proven vet WR is not going to come easy this year because I can't think of anyone there. I would like to know who you have in mind personally. The only guy I could think of is Brandon Marshall but I don't know how much interest the team would show in a rental player who keeps bouncing around for unknown reasons.
