Fantasy QB Quandary- When to Pick One?

[So Be]

My view is that I want a top gun at QB and do not want to wait until the 7th round.
My options with value and VG value;

Allen- 3rd or 4th round
Herbert- 4th or 5th
Mahomes- 4th or 5th

Jackson, Murray, Hurts- 5th or 6th

I want one of these guys and my best pick would be Herbert in the 5th.

My thinking is that my top 3 played every game and went off for 30+ points on some. Others may be only a few points less on average but missed games and do not have the explosion of the top guys. Just my view.

As with any of these questions it depends on your scoring system, league size, historical predilictions etc. In my league QBs start to go in the first or second most years, and I start looking in the 3rd but if my top tier is gone earlier I might wait until the 5th or 6th and then add a backup with a complementary schedule quickly after that. One question to ask is whether your team can compete without a top 5-10 QB, is the drop-off from that group too great to risk it? In my league the QB position is usually worth 25% or more of weekly points so it is imperative to have a good one unless your team is super stacked at most other positions.
