It'll be very interesting if they don't take any QB.
I'll naturally be concerned it's because Ron is deluded into believing Allen just needs some time playing behind Fitzpatrick to put it all together. That's the sort of thinking we've been trained to expect for years. Hopefully it would be because they recognize that dropping young QBs into a half-built tire fire almost never works, and that the better plan is building the shit out of the team before getting someone next year.
Warning: long post incoming.
I've been thinking a lot about this and I think your last sentence is spot on. The only QB I wanted them to trade up for this year was Fields but I think I'm ok with their approach of building the team first for a few reasons.
First, Fitz is as good a stopgap QB as you can find and they can probably get 1-2 years of above average QB play from him. Also, this year demand was the highest I can remember for a QB with relatively low supply. I think over half of the teams in the league were in the market for a QB this offseason and that number should decrease fairly significantly next year. Here are the teams that I think will or could be searching for a QB next year: Denver, NYG, Philly, WFT, Atlanta, Pittsburgh, and New Orleans. Of course some team(s) with high expectations will totally tank and decide to move on from their QB so this list should grow but this year's list of QB needy teams was insane and some teams who could have been in the mix next year (Minnesota, Houston, Tampa, New England) all took young QBs in high rounds so they'll likely give those guys a few years to pan out.
Next, there is a pretty decent chance that they're actually a good to very good team but won't have a winning record this year because their schedule is brutal. Outside of the NFC East they have to face Tom Brady, Patrick Mahomes, Russ Wilson, Justin Herbert, Aaron Rodgers, and Josh Allen. That is tough -- they could be a very good team and still be under .500. It would suck to have traded away next year's first with a realistic chance that it could be a pretty high pick. I also would much prefer the route they're taking now and take legit talent in Rounds 2 and 3 who could start at other positions rather than waste a pick on a developmental QB who has very little chance to pan out.
Third, I think next year could be the year to go all-in and trade futures to move up if need be. They'll have had three years of solid roster growth, Ron's culture and schemes will be fully established, and the roster may not have a lot of holes if their draft picks pan out which honestly they've nailed the last few years. Timing could be right to go get their guy.
Finally, we have no idea how the college football season will play out but there are 4-5 QBs right now marked as first round picks so there should be talent available. Plus, who knows how the Rodgers and Watson sagas will play out. So yeah, I too am concerned about not having our long-term QB on the roster but if things play out like they could I think they have a solid chance at filling that spot next year.
... of course, the elephant in the room is that they could actually be very good this year and then finding their QB is going to be even harder but let's cross that bridge when we get there.
