That’s true. I don’t know what these GMs are thinking, but when you are drafting in the top 8, that usually means your team sucks and your roster is busted. Not a great fix to throw away future picks to get 1 guy who isn’t a sure thing.
If I am the Chargers GM and I rank the QBs in this order:
Herbert, Tua, Love for instance…
If Miami grabs Herbert, then I take Tua. If I am super scared about Tua’s injury, then I trade down and grab Love and add an extra pick or 2. If I think my team is close to competing, then I only take Herbert if he falls to me and if he doesn’t then I trade a future pick for Dalton for the stop gap.
None of these teams are a rookie QB away from being good, so throwing away future picks is really not helping your new franchise QB.
