I don't know why I keep smashing my head against this brick wall, because it's surely not worth it.
QBs are pretty regularly overdrafted due to positional value and scarcity, more so than other positions. It's basically baked into their evaluations at this point. I think most reasonable people can recognize that. Teams regularly show they're willing to take a chance on a QB, and pay a steep price to do it, even if they're not as good or polished at their position as other players.
I don't think the Ravens should or would reach to draft Will Levis in the top 10, but might otherwise consider it in the very unlikely event he fell further down the draft board. This isn't exactly a hot take. In fact, I think the way they've run their front office and drafts over the years backs that up. But based on where Will Levis is projected to be drafted, and how other QB needy franchises will value him, I don't see it happening. Even more so with Anthony Richardson.
And I don't know what you're trying to accomplish with your Brock Purdy crusade here, but recognition of the coaching staff and supporting cast he's working with isn't "explaining away" his success. They're major contributing factors, period. Kyle Shanahan being up for COTY doesn't have to be a slight to Brock Purdy. I don't know why you and others on this forum insist on these discussions being so black and white.
Nobody is making anything black and white. In fact, the only black and white comment anywhere in this exchange is the (apparent) certainty that you have that Levis and Richardson will be overdrafted, (almost) certain busts.
I'm not on a "Brock Purdy Crusade," as you said, but it's genuinely weird that you appear to give most of the credit to Shanahan and not to the guy who is actually making the throws. Your first response to him even bring brought up was to credit his coach and system. What he's doing is pretty extraordinary no matter who his coach is. Being quick to credit his coach and system and only (begrudgingly) admitting that he's playing "well," is minimizing what he's doing. It just is.
Anyway, the point is that you just never know what these guys are going to be. It's easy to say in hindsight that you could expect it with Jackson and Hurts because of their college resumes, but lots of people who's job it was to evaluate talent thought they shouldn't even play the position in the pros, and both are likely to have been picked after Levis or Richardson will be. Some QBs in the draft might go a little higher than another player of similar talent would at a less scarce position, but it's not like teams are leaping 2 rounds early for a fringe NFL player because they're so desperate to get it right. We also notice those that bust more, because it's such a high profile position.
I have confidence that if the Ravens go a route that requires a first round QB, that they'll get it right.
