In all seriousness, the only QBs from rounds 4-7 from the last 10 years who have been any good are Kirk Cousins, Tyrod Taylor and Dak Prescott. For each one of those guys, there are 15 guys picked in those rounds who never become anything at the NFL level.
You don't need to draft a QB early every year, but if you're going to rely on the middle rounds as your pipeline of young QBs, you need to draft them often because the history of those draft picks overwhelmingly shows that they have roughly a 90% chance of NOT developing into a franchise QB.
When someone tags a player as a "developmental" QB, that just means they're probably not going to work out. If you're relying on "developmental" players, you need to be developing a few of them to play the clear cut odds.
I couldn't care less if the Bills draft another QB. I'm simply pointing out that the argument for not drafting one because we have Jones is a severely flawed argument.
