I'm wondering how many people are going with your line of thinking because of the no flex.
Normally I'd say there's good value at qb in 3-5 but in your case I'd be looking to pull the trigger in the second. You still might get a nice find in the third due to people taking the top receivers and the big 3 t/e in the second.
Take this with a grain of salt, as it's only my second year playing.
