If you NEED a QB and you are in position to take one you like from your scouting, then you DRAFT HIM every damn time.
You NEVER pass on a QB in that circumstance. Its the most important, impactful, and difficult position to nail down. Never Never Never
If you have a bad, OL you still draft a QB If you have a bad receiver group, you still draft a QB If your coaching staff sucks, you still draft a QB
None of that means you ignore the other issue or don't try to address them. And whether then rookie sits or starts right away is another matter I could see going either way. The NFL is trending away from "sitting a QB for years". That rarely happens anymore. Unlike GB, most teams don't have a HOFer still on the roster playing well.
But I'd far rather draft a QB I like when I have a shot at him and make him sit his rookie year while I get other problems addressed, then NOT HAVE ONE.
For years around here during the Cutler-era, we all bitched about how the Bears hadn't "invested" in the position.
Agreed my point was don't reach out of desperation and when you draft one don't throw him out there right away
No one is saying to "reach". Occasionally there are drafts where no QBs look 1st round worthy. Rare, but it happens yes.
