Why are bad teams obsessed with drafting 1st round QBs

Why not build a great team first from the ground up and then attract or trade for an already good QB when you’re ready to make a run?

1st round QBs rarely hit and you have this perpetual cycle of failing.

I’d rather have a team that’s. QB away from a title then having a QB and missing all the other pieces… and continuing to be bad, losing all the other high draft picks along the way….
