Great breakdown, I always appreciate the work you put into laying things out like this, so thank you for that!
I agree 100% on Karras. I'm not opposed to bringing Brown back too on the right deal, but there are going to be some tough decisions to make in general so if we only brought one back, I'd prefer Karras and plug Onwenu in at RT. We should also sign a veteran swing tackle though (if Brown is too expensive) or maybe try to get one in the middle rounds of the draft (riskier move).
If White can play, I'd like to give him a shot, but I'm skeptical he'll be the same guy. It might be time to look for a younger 3rd down back (still holding out hope for JJ Taylor, or maybe Stevenson can fill some of that) and bring back Bolden as the "in case of emergency break open glass" kind of guy. He did yeoman's work in that role this year, but I hope we improve.
Folk we need until we're sure we can get a younger upgrade. As we saw with Nordin and Rohrwasser before him, that is never a sure thing.
Slater and Hoyer should be short money and no brainers IF they still want to play.
Gunner is the one I go back and forth on. Shouldn't be expensive, but he hasn't grown as much as a WR as I'd hoped. He also wasn't nearly as dynamic as a PR this year as he was last year. That said, I hate giving up on those dirt dog types before we see where their work takes them. And right now we don't have another PR I trust to make good decisions. So I'm leaning towards bringing him back, but I'm not gonna spend more than a few moments thinking about it if they let him walk.
