I disagree with your premise #1. Once Allen and Shelton return then I consider our OL plenty good enough. Already discussed in another thread.
I’ve already opined that acquiring a ‘solid’ Edge would be desirable. It’s #1 on my to-do list. Not sure we can get to another SB with our current edge roster, frankly.
I think it’s imperative to bring in a ‘solid’ RB, if only for injury insurance in a potential SB run.
I think we should always be thinking SB run at least as long as AD is still playing.
Of course, I will support any decision that Snead/McVay may make. They’re the ones with the resume.
